Might be so with a mechanical shutter, but we don't know what exactly is going on with an electronic shutter, do we? There's software involved and it's hard to know what's being done in camera, there might be some magical readout mojo going on which you might not be able to emulate in post.

Funny, if they would crap their product... and some group of geeks would develop some crazy hack to lift their limits, then would be a terrific steal...?  : D
C'mon, where do you find the best tech in the smallest 8K/4K package (yes, price included) ??!
Let's get a fair perspective on here, give a break to your (d)efective nonsense : ) With or without they had somehow clippled their hot stove in form of mirrorless camera only for SELLING their higher price range, they've offered the best they can in a REALLY portable capture device -- add external recording and stop whining about your VIRTUAL sex life with a girl you're not even thinking to date, go figure to live with! : D
 
(BTW, I didn't buy it yet, I had just placed a pre-order so to comply now, this camera will stand by me and letting run 'n gun no matters how many quirks we're still reading in these pages...
...only because you'd actually and merely love to pay it for a perfect angel just like heaven!)

So first off I come from Live Events so my testing of the A7Rii falls into the pocket of shooting all day 1-8min clips and not getting a second chance. For that reason I am going to say upfront I would never walk into live event without a second body strapped to my hip especially with this hot 4K little monster. Now I shoot 1-8min takes because I lived through the 7D days of clips deleting at random so honestly I shoot smaller sized clips based out of habit. Even for toasts etc, we have multi cameras running so its no biggie. 
So I decided to run the new camera until I got the notorious temp icon of dread..... My take on that moment is what if I was on a  shoot how would I adapt aside from dipping the camera in ice or holding a cold beer to the of the back screen. 
Shooting 4K 100mbs FF 3200ISO Image Stabilizer On
 I received the temp icon at roughly the 25min mark shooting 3-5min clips back to back. I quickly switched the battery out and than decided to use just use the viewfinder(not as heat heavy on the camera). I was able to from that moment shoot 3-5min clips for 40minutes without a single warning. I also switched over to S35 somewhere in the middle just to see if it would heat things up. Total Runtime was 65minutes without having to shut down /cool down. If my card did not fill up I would have liked to go even further.
I know its not ideal, but if the moment presents itself swapping a battery and switching viewfinders is a whole lot better than waiting for the camera to cool off. This also does give me hope on the A7Sii body re design to fix the issue as its lurking around the screen more than the sensor.

Yeah, but trying to nail down the specifics, like what lens (Samsung vs. other, OIS vs. no OIS, 1.02 vs. 1.03, etc.), what situations (long vs. short), what kind of movements, etc. I will experiment myself and post, and hopefully we can put all the experiences together to come with a guide of sorts. Everyone with NX1: please test and post your experiences/footage!

Yeah, I'd say it depends on your priorities. If you love to crop, use lenses without IS handheld, and regularly print 24x36 and larger, the A7RII is for you. If you prefer cleaner low-light images, take long video clips that can't be paused for overheating, and don't mind an external recorder, the A7S is becoming a pretty good value. 

Always decide what you want out of a new purchase first. Then, and only then, should you start perusing cameras to find one that fits your wish list.

Well I have to disagree... Sort of... The a7rii is just as much about 42mp images as anything else. So if the goal is an all around camera, then the clear choice is the A7rii.

I've seen Olympus' IBIS to beat Sony (but no 4K, no 8K), Samsung's AF to beat Sony (but again, something to not offer: 8K for large prints in this case). The whole point IMO is the fact no camera is better than the other but, that camera is better than the other for your needs. My whole beef, actually.

Making definitive statements about it being useless for anything is complete hyperbole and a gross overreaction. The hot pixels are in every Sony sensor camera. If you take a long exposure with the lens cap on, push the exposure 5 or 6 stops and lift the shadows all the way and then blow up the image 400% there will be noise. Try the same thing with Canon or and m43 and it won't be any better. You can see the same thing on the A7s and D810 here: http://www.fredmiranda.com/forum/topic/1380165/2 and its also in the A7r files. 
Capture One easily eliminates all of this with no loss in detail. You can do long exposure noise reduction in cam and it takes a black frame and does the same thing. This does impact people stacking 200 images of star trails as that's not a practical workflow. But for most its a simple fix. Really. 
All of these declarations are such overreactions. First its the greatest camera ever! Then it overheats shooting non-stop 4k so its junk! Now there's noise in the shadows its useless! Take a step back, the reality is definitely somewhere in the middle. I've seen some pretty damn impressive landscape images from the A7rII and there will be many more. In no way are any of today's cameras holding you back.
The A7rII certainly has warts, but I've said it before and I'll say it again - its a powerhouse camera that can replace the A7s/A7r and an external recorder for most - except for those that need lots of continuous 4k recording. But it still adds IBIS, 4k internal, better AF, faster startup time, 42mp (18 in crop mode) more adjustments (like minimum SS with auto ISO, assignable record button) and so on...

When recording for long, turning the lcd brightness all the way down help ALOT, on my nex 7 i can only get around 4 min in hot sunlight until it overheates. When i have screen all the way down i get 15min

I don't feel I'm getting defensive - I just think this forum is quick to jump to the most ridiculous conclusions about products, and completely rule out products based on one, single, unscientific 'test' done by someone who is likely a newbie.
That RED Dragon footage I saw that was insanely noisy, had blown-out highlights, crushed dynamic range, terrible skin tones etc. Instead of saying 'wow, how terrible is the RED Dragon, I'm never going to use it, it's a weak camera with terrible colours, and dynamic range and awful low-light ability' - I watched footage from others and did my own tests and came to the conclusion that you can get really beautiful looking images out of the RED Dragon, and that awful footage I saw was simply user error.
 I've seen 5D stills that are awful. I could have said 'man the 5D is just a terrible camera to use for portraits, obviously.' Of course, we all know that to be untrue - the 5D is a great stills camera. I'm not going to judge it based on a small number of people who aren't photographers, or don't know how to use it or expose their photos.
No camera is perfect, and learning more about how they perform in certain situations is always good, and allows you to find strategies to compensate - but let's get some perspective here. And lets do our own tests before jumping to random conclusions. As I've said many times - people here talk at length about how 'awful' the colours from the A7s is. I'm yet to have the same issues. I do have some issues sometimes when skin is under-exposed, but overall I don't get anything like the issues that many seem to have here. By doing my own tests, I've figured out what I can get out of the camera, and how to compensate for other things in order to get great images.
I didn't look at posts from people who were only using the camera for the first time and couldn't expose their images properly to base my decision on purchasing it.

I'd say wait a bit more for some more long term reviews of the a7rII comes out and make your choice then.

Not perfect, but actually good news here:

And I apologize if I posted this already I've been very busy. I tested this again multiple times last night but instead of triggering recording on the camera I triggered recording on the shogun. And the result was that I could record continuously until one of the batteries ran out, usually the cameras, sometimes the shoguns. At most I got about an hour and a half with no overhear warnings; when it shut down is because the battery was exhausted ( as per the message on the screen). I did not test on external power. If I triggered the recording in the camera, making sure that internal recording was off, it would overheat in 30 minutes. I don't know what's going on here and have passed my thoughts to Atomos. My theory is that processing is kicking in when you click record even though it's not dumping to the card but if you just let it roll without hitting the record button on the camera you get the output right from the sensor. I tested the same theory with the RX 100 Mark four. I got the same result. That camera records for less than five minutes before overheating if you record it on camera but if you just roll from The HDMI you can get an hour out of it before the battery dies. Again, with no overheating. Weird."

Thanks Andrew for the info - it's really crazy, the camera has so many great and logical aspects, but Sony still finds a way to make things complicated.  This limitation means i can either have a proper magnification mode for video and can only shoot 36MP photos, or i have a limited magnification and can shoot the full 42MP photos.  Or i have the best photo resolution and the best magnification, but can't frame right before recording a video!    To make things more difficult, Sony wants us to buy several functions like the timelapse mode from their playmemories store which right now offers ca. 30 apps that could be installed on the camera.  I would understand that for special applications, but not basics like a timelapse in a 3500 euro camera.  At least among these 30 apps there are ca. 5-10 usefull tools that the competitor brands don't have, and some are free as well.  It's just pain in the ass to install and manage.
All in all the A7R2 feels as if i suddenly have the power of a second 1DC, GH4 and D800/5DsR available.  Just if i could choose, for each specialized purpose i would still prefer to use the Canon, Pansonic or Nikon cameras.  In cases where i only can bring one camera or i need the special strength of for example a second 1DC, the A7R2 now is a great choice.  For each user who only has a 5D3, D800 etc, the camera also is a new great alternative.  
In general the camera doesnt offer better 4k video or phot images than the 2012 technology of a D800 or 1DC.  It's a bit sad, because aside from a stop more in highlights, even the new Red Weapon doesnt seem to offer a different image compared to the 2011 Red Epic MX.  Aside from 1-2 stops more in dynamic range, the C300 II probably also doesnt deliver a better image than the 1DC.  This means that until the year 2018 we can be stuck with the same image quality options that we had 6 years ago.  At some point technology does come to an end, which is seen in the audio world, where certain speaker / microphone standards have not been topped since 20-40 years. 
Sony has a really nice 50 megapixel sensor that's above what's in the A7R2 and right now built in the Pentax 645z and a Hasselblad and a Phase One.  Unfortunately that only works with medium format and will have sensor cooling issues as well.  Above that Phase One offers an 80 megapixel sensor, which is only usable until ISO 400(!).  I guess the next 2-3 years will be about making existing technologies cheaper, products smaller, and combining more features.  But the image quality has reached a certain limit.

From same original poster/shooter:
 
 

Branding!  It's all about getting people familiar and comfortable with the name brand.  Look how it's worked out for Nikon and Canon.  

Because if they don't do it somebody else will

A free non-linear editor that will be good enough to do a lot of work - and a great organizational tool like Resolve futher makes me think this is going to be a game-changer again.  Why put all this stuff out for free?
 
I have no clue - guess it gets more people to like Blackmagic.
