The reassuring thing about the Pocket 4K is that BM are already taking it around to most of the Pro Sales and Rental houses here in Australia and letting people (rental managers, sales people, and industry professionals) play with it. We are still four months away from its scheduled release and the camera is doing the rounds. While they do state that it's a 'preproduction model' so not allowing anyone record footage with it, in terms of issues, these should be greatly minimised as they are getting feedback a long time before release.

When this camera arrives there will be no more rain Jon.
There'll only be sunshine and nice things for everyone.

You know you can decide your shutter on a GoPro with Protune? Gone are the days from the Hero3 where exposure was automatic unless you want that.
 

Sony already has problems with overheating so that's probably why they can't run their sensors any faster.  Even the latest RED cameras are fairly slow sensor readout even compared to Blackmagic.  That's one of the compromises when you build a larger, higher resolution sensor.

We plan for the beer. If any footage ends up actually being captured, that is just a bonus.

I’m always impressed by those here who can tell the camera from the footage. I admit to struggling to see the difference even when I am  told where to look and what to look for! 
It’s like a game of chess - the colour grader trying to make the footage from the various cameras match and the eagle-eyed EOSHDer trying to spot the difference...

There is a deep divide in the vlogging community about where the flip screen should be..  those that use in-camera sound and prefer the screen flips over the top because it looks more natural if they look at the screen while shooting, and those that use an external microphone which is mounted in the hot-shoe of the camera and therefore they prefer a side-flipping screen like Canon.
.....then there are the Sony shooters, who focus on their hand and then just stare into their 16-35 hoping they're in frame!!!    

That's an interesting point.  Many of the reasons it's not suitable for me (as a specialist camera) make it more suitable for the average consumer.
Phones still have huge screens and are already in your pocket, but the 19mm lens does help somewhat.

This is 84.90euros in my country. This is seriously an action camera for the masses. Comes with a box full of accessories inside. Is it as good as a GoPro6, or even 5? Of course not, but most people will be happy to spend a lot less than 100euros (this can be an impulsive buy for a lot of us, even my I consider 84.90euros for a nice little gadget a very fair price), and it comes with 2 years European warranty (German company it seems).
@kyeWaterproof mobile phones can, but it is not advisable to swim with. Even action cams without housings have to be cleaned, and properly dry out, but you can shoot somethings on the beach (not inside the sea, salt is killing everything, even human hearts!), near a pool, or on a river (canoe-cayak!). I would call them splashproof.

As someone with a pretty average life (job, family, house, car, etc) who shoots with my GoPro a lot I actually disagree about them being good for family events.
They're wide angle, which means that you have to either zoom in, which is pretty difficult to hold them remotely still (unless you rig them up, in which case just use a larger camera with IS) or film everything close up, which is kind of strange and the lens distortions are EXTREMELY UNFLATTERING to average people (who don't have the figures of models or people used to seeing themselves on TV).
I actually agree with @Kisaha that the best cameras for recording normal life is the smartphone, as it has many of the advantages but also lots less disadvantages.
Also, I think that action cameras are cameras that require huge amounts of editing to get good end results from.  You film things close up, film things that are moving quickly (either in slow-mo or real-time), put them over fast music and do a fast edit with lots of cuts.  That's the GoPro aesthetic.  I think this video proves that:
In researching a replacement for my GoPro I was reading forums about potential other cameras, and one person said their camera recorded nice quality at first but later on in the file the quality reduced.  One of the replies was to only shoot short clips because "long clips are really boring" - obviously that person assumed the clips wouldn't be edited at all!
Last month I shot a film at a club for a friends birthday (I posted it in the GoPro replacement thread) and I shot it with my GoPro precisely because I didn't want to pass my phone to drunken adults in a club.  Plus I wouldn't have gotten my DJI Osmo Mobile 2 past security - they took a few long looks at my Bobber handle that I had on it.
Completely agree.
I did actually go swimming with my iPhone 8 deliberately at the beach when I first got it as I was wondering if I could replace my GoPro with it.  I haven't edited the footage yet, but I can tell you the 1080p240 at 400% quality from MoviePro app looks absolutely spectacular in full-afternoon-sun, the screen only worked sometimes, and it took a few hours to dry out afterwards before it would charge properly again.  I actually did what you're not meant to do and I plugged it in to charge, so it should have killed something but I was lucky.
With your phone you don't have anything else to carry, you get a nice large screen (huge by camera standards), you can edit in-camera, and you can upload direct from the device.  Action cameras require SD card adapters a full computer or hours of file transfer time, and all the stuffing around that keeps an army of post-production staff employed around the world.
I have a big camera with zoom lens which is good for everything except being discrete (or wider than 24mm), my phone which is very discreet but no zoom, and my GoPro which is waterproof and very wide.  In this sense it's a specialist camera used for very particular things.

I thought they’d already discontinued the pocket ?  Watch that become a cult camera if it isn’t already.
I think they’ll keep the micro going for some time.  It’s really a different camera.
In the photo above the camera has a wooden camera cage, a Noga arm and a BMD 5” VA as the operating monitor. On front is the SLR Magic 10mm T2.1.  I’m manually focussing myself, using peaking on the VA.  
By way of example almost all of this promo is either Ursa Mini Pro or Micro using that exact rig.
This whole scene is shot Ursa Mini Pro
 
 
I have used a LOT of Ursa Mini Pro and Micro in the resident.  Not just as an insert camera, but shooting whole scenes using only the Ursa Mini Pro.  Most scenes have a mix of Ursa Mini Pro and ALexa, and I’d estimate more than 40% of the show is Ursa Mini.
I tend to use the micro camera for these kinds of surgery shots where I can very easily reach into the scene and get super close before diving down to almost inside the surgical field, and then transitioning back to another actor. It keeps it very agile and alive shooting this way.  I’d anticipate the Pocket 2 will replace this rig for these kinds of shots.

I pretty much use the terms "guerilla filmmaking" and "run and gun" shooting interchangeably. They're both war metaphors. The shooting style is applicable both for when you have permission, and when you don't, when you have actors, and when you're filming real people. There's also "one man band" which fits in a similar mould. To me run-and-gun is a relative term. A Hollywood person might use it to describe a crew of 10 people, LOL. If there is a difference between the terms it's that "guerilla" implies an ethos - get the film shot by any means. When I shot the piece below, for instance, I never had more than two crew members and was usually alone. All of the rooftop shots were a location that we sneaked onto (and setup a slider and handheld LEDs, ha). The terms guerilla, run-and-gun, and one man band apply to nearly every shot: 
 

Seriously, great video!
I consider all the action cams unacceptable for me. What I use mostly (not waterproof) is an old NX3000, an APS-C 20megapixels very very small mirrorless woth the native, tiny amd great 10mm 3.5f fish eye.
The 1" Sony must be great as well, but the other option cost me less, 3 years ago, and arguably the quality is great.

The quality of the final video is pretty good for a gopro!
The flare is caused by greasy lens, you can avoid it if you are not using the skeleton case, but the frame. Of course in this case the camera is no longer protected against the elements.
Almost all of the action cameras are using the same sensor, the low light performance is most likely the same. With the gopro's you can use a special professional mode where you can turn off all of the precessing.
For this mode you need Protune 2.0 capable camera so Hero3+ at least. Use the usual Protune, Native WB, Flat settings, fix your shutter speed (1/50-1/100) and instead of "max iso" choose "fix ISO" value. In this mode the in camera noise reduction turns completly off. In this case you get a very detailed (and of course very noisy) results till iso1600, but after NR the final footage can look better.

Older blackmagic cameras with gen1 color science (BMCC, BMPCC, Micro, etc.) have much less sophisticated color science than the modern Blackmagic cameras.  They look good with nice dynamic range and good skintones, but when you want to match them to better cameras, it's a little bit harder. It probably has more of a baked-in look that people prefer.  The color science of the newer 4.6K Blackmagic camera is very nice and matches much better to higher-end camera systems.
I think mainstream is a good thing with this new Blackmagic camera as it will get their name out there even more to the general public.  If they sell a large enough volume of cameras they might even make other manufacturers reconsider the features they're putting in the cameras which will benefit everyone.

It may sound like I’m a newbie to stock footage/photos, but actually I still have a portfolio of footage which I put up onto a few agencies about ten years ago. I just want to get back into it again now as I have a bit more spare time.
You are absolutely correct in not being able to predict what sells. My best selling footage is a of a hand (mine) putting coins into a piggy bank, I shot that on a Canon 550D (T2i) 8 years ago with the lighting setup, shoot and editing taking not much more than 20 minutes in total.
It’s an appealing business model whereby you can have a long earnings tail from your portfolio, but I am the first to admit that it is really competitive and very hit and miss. You also need a huge number of clips to get over its randomness,
I’m not considering this as a main earnings stream, but more of an add on to my client work and other earnings streams.  

According to the sticker on the card, this one will just about manage, and is also the cheapest I can find... Whether it actually holds up is another story though: https://www.integralmemory.com/product/ultimapro-x2-cfast-2.0-memory-card

IIRC the fashion is to have shallow depth of field but the killer technique with Sony users (no front-facing screen there either!) is to extend your arm out with fingers pointed up and focus on them, as when holding the camera that's the same focus distance as hand to your face..  :D
In reply to the above and also in general, we're in (yet another) situation where worlds collide.
World #1 is people who shoot RAW and see the camera as a tiny cinema camera.  In this sense SDI > HDMI and professional standards > consumer standards.
World #2 is people who want the 'best' ILC camera for under $2000.  In this sense, HDMI > SDI, consumer standards > professional standards, and front-facing buttons/screens/etc are nice features to have.
Neither world is wrong, it's just that before the DSLR revolution and YouTube these two worlds had never touched before.  Now they're in full collision mode.  Camera companies are trying to make products that appeal to both worlds and failing to connect, and both worlds look each other up and down then go back to whispering in separate groups like 10-year-olds in the school-yard.
In a decade we'll have worked out how big the market for online video is, how many people it can sustain at the various levels of quality, and what products make sense.
At the moment it's a mess, where the 'best vlogging camera' debate includes your phone, the RX100, the Canon M50, the Sony A7III, and the Pocket 2.  Any application that includes tools as varied as that lineup should indicate that we still haven't worked out what the hell is going on yet.

Its unfortunately very common and is actually at its most prevalent on what you would think was the safe side of the fence which is in the accredited areas themselves.
Its only happened to me once (touch wood) at a final in Berlin a couple of years ago when one of the stewards stole my iPhone off the top of my peli case while I was shooting the trophy lift over the other side of the pitch.
Funnily enough, it caused me far more of a problem than if he'd took a camera because it had my boarding pass for my flight home on it, it was the GPS for me to drive back to Leipzig because that's where I'd flown in from etc etc
I have quite a few of those dividers and use them for turning an Ikea rucksack into a camera bag but also for quickly packing real camera bags as I swap between different capacity ones so its easier to keep certain lens combos in the dividers all the time and transfer them in one go.
 
 

Similar advice to when you don't want your camera to get stolen
I've been reluctant to go for a larger sized camera body, as before I got into photography that was how I judged if a person was a professional photographer (wrong I know, but it is what it is)!
In terms of looking the part, I think I've got that down...  I just got back from a 10 day trip to the Northern Territory of Australia and in addition to the shorts, t-shirt, backpack, and scowl from wrangling kids I also bought one of these so I didn't burnt to a crisp in the sun:

I'm pretty sure that no-one, after seeing my hat, had the inclination to take me seriously

For me it's actually slightly different - I'm shooting totally legally but I must still be clandestine.
I'm shooting in places where people can shoot video of their kid with their phone, but if I shot the same shot with a C300 then I would get kicked out or get hassled or attract unwanted attention from the surrounding public.  I'm not doing anything wrong, but I also want to use a better camera than my phone without getting hassled, thus the need to be clandestine.
With your 5d3, what lenses and sound equipment do you use?  and where do you shoot?  I find it to be a question of how big your camera setup looks that is the main factor unfortunately...
