Why will you choose this over another camera in the $3,000-4,000 range? Seems like there are options that are a better choice for someone doing video. Or do you need something that can do stills and video well in one camera? The dual pixel is nice to have but you can now pick up a new C100 mkii for not much more money.
You think these specs "rock" compared to what other companies are currently offering and what they'll be offering in the coming years? I'm not seeing it. But I'm sure Canon will sell tons of them because so many are already heavily invested in their system and this will be more than enough for most of them.

Nope, what that link says is:
"for the slow motion 120fps of HD video"
Which means it could either mean 720 or 1080, being Canon.... I'd lean more towards suspecting it is 720 than 1080

Yeah most people don't have particularly demanding needs and "good enough" is all they need for now. Unfortunately I expect the Canon fanboys will lap this up.

Probably cause they limit stuff like that to what they consider their cinema line and they don't see this as one of those cameras, though I'm sure they expect it to get a lot of use from indy filmmakers. 
Yeah, it's remarkable what the GH4 can already provide. Now imagine how much better the GH5 and GH6 will be. Both of these should come out before we see a 5D mkV. I know cameras are more than a spec sheet, but I'm not understanding the excitement. Maybe it will be incredible though.

A good "in-depth look at the video specs of the Canon 5D Mark IV", thanks for sharing it Andrew!
@gt3rs, don't get your hopes up. A 4K UHD crop from a 30,4 Mpix sensor will result in approx 1,75x crop. A lot closer to Panasonic Gh2 1,86x video crop than Canon APSC.
IMO, Canon may either offer a 1,75x crop 4K UHD video mode, or a full frame 4K UHD (FHD resolution wise) with line skipping and a blur applied to it to kill off the moire (like on 7D mk 2 FHD), or both modes. Laughing date is near so we shall rest easy in a couple of days.
@Mattias Burling, I don't know what Gh4 or Sony cameras you've used, but my "special" Gh4 trashes any 5D mk 3 regarding video quality any day and XC-10 was the biggest joke Canon has ever made. :))

@Mattias Burling "4K from a GH4. Sony A7s or other low bitrate shooters doesn't look as good as upscaled HD from a good camera imo."
A carefully shot and edited 4K image looks much better than any Canon FHD. I've used for meany years the 5D2 for video work and was a revolutionary tool for it's time, but now even in RAW looks old. It is ok to have different preferences and opinions but what you just said is very untrue. On a 4K or bigger screen, FHD looks pour in comparison to a 4K image.
Just remember, Gh4 + an external recorder brings 4K at 10 bit and 4:2:2 chroma sampling to the table, a very good image at a price under 5D mk 3.

Thanks for posting the video shot with XT2. I'm absolutely intrigued by it and if GH5 won't be something exceptional I'm seriously consider the switch to Fuji.
As I see it now, XT2 is what I always wanted: an APSC sensor camera with beautiful 4K video from resizing (no crop, no line skipping etc), great colors, low noise, no overheating (with optional grip) a nice design without ergonomic problems, very good photo quality, good AF and a very good lens collection!

The XC-10 305Mbit/s codec is nothing extraordinary, it's just another intra frame (ALL-I like codec), the 1Dc and 1DX mk2 have higher bit rate, although not 4:2:2 color, but the image out of them look so much better.
I can't really understand what you find appealing in XC-10? My experience with it left me with a bitter taste, the 4K image is very soft (more like 2,5K), DR is BAD, nowhere near 12 stops, the AF is slow and the combination of a small senor and fixed dark lens makes the image very uncinematic, and above all the price is unrealistic + the price of the Cfast cards is very high.
I also can't wait for the GH5.

@Andrew Reid
A very good article that's right on spot about 1Dx mk 2 and Canon DSLR video strategy! Unfortunately  

With the release of a $6000 1D body that has no peaking, uses an ancient 8-bit codec and has no log, don't expect the lower range 5D body to be whipping those specs...
the writing has been on the wall for so long it's faded and someone has graffitied toilet-dicks all over it: Canon has seperated video and stills for the foreseeable future.
sad times.

I'm strongly disbelieving the GH5 will feature the same old 16 MP sensor found in G7 (aka GX80 + stabilization), this is a pure speculation with no foundation what so ever in it!
All the rumors until now state it will have a totally new sensor specifically produced by Sony for Panasonic with a multi aspect ratio which measures 18,9 mm per 13mm, with 24 channels readout (cooper wiring and probably BSI), 6K video and 60p in 4K. If this turns true, the new sensor will have around 21+ MP in 4/3 and 18,6 in 16/9 (to accommodate the 6K resolution).

Don't confuse mega Pixels with mega Dots (R, G and B sub pixels). This screen has 5 Mdots or 1,66 Mpixels and the Leica has 4,4 Mdots or 1,46 Mpixels effective resolution!

NO, I wold not like an APS-C sensor on Gh5!
A multi aspect m4/3  24 MP sensor with 6K video recording, 4K downsampeld from 6K, 10 bit and 4:2:2 internal recording, better AF (especially for video), a better audio DAC, Vlog 2, 60p 4K, better DR and Low light capabilities and a better body would do the trick at 1799$ for me.

I think the most forgettable upgrades have been to the Rebel series actually... they make the 80D look like a quantum leap!
600D through 650D, 700D, was embarrassing.
It looked like the only feature they added was lower manufacturing cost and at one point a grip material that turned white.
Yet the sheep kept buying I assume.

The first camera I ever bought was the Canon XHA1s and the the 60d. At the time I was gobsmacked by the entire DSLR video thing. 
Now I realise Canon were never really using their stills models to appeal to video professionals. None of their DSLRs have ever had basic video features.... even the 1DC. 
Canon want video professionals on their C-series, and it's as simple as that. 
Sony offer ridiculous specs and give you everything as if it's a laugh, even if it means a little overheating. Or shitty colour. I like Sony. They will get better with the nitty gritty. They are a sensible system to buy into. 
On big commercial sets, if I ever see a DSLR it's the 5D III. And the C300. Saw an FS7 once. And the JVC LS300 for that matter! 
I like Canon's reliability and pleasing images though and I bloody hope they would give their low to mid lineup more attention with video, but it's not going to happen. (Or save up and get a 1DX II + 6 million hard drives). 
Meanwhile... Panasonic, Sony and Blackmagic all offer many solutions for us video nuts that offer a lot for every little. The only thing holding you back these days is yourself. 
On a positive note to the 80d, I'd rather use this or any Canon for stills than any other brand. They just look better, don't they?  
 

Strongly doubt Panasonic will go S35 for the GH5 and make obsolete overnight their entire lens collection!! That is just business madness.
You could say "oh but it will still work with all the m4/3 glass in cropped mode". No, just no. This could spin into a marketing disaster for Panasonic, as it would be a very bad look for them and would send out a terrible signal about the m4/3 system and its future.
MAAAAAYBE they might do S35 with an "AF200" (kinda like an ultra low end Vaircam S35), but absolutely not with a stills camera.
All Panasonic needs to do is DCI 4K 60fps with 10bit internal and people will go absolute nuts over it buying the camera, and then Panasonic will easily maintain their lead over Sony for another year or more.
But I won't deny, also getting as a bonus a multi aspect ratio sensor like in the GH2 would be nice. This would give it a "larger" sensor kinda, but still would work 100% with all their existing lenses. Plus of course I want full sensor read out for 4K with no additional crop.  VLOOK or raw to an external recorder would also be nice too. When it comes to ergonomics, if they took a leaf out of Sony's book and had a detachable handle on the GH5 like on the FS7 so you could rig up a GH5 into a mini FS7 style camera that would be aaaamazing (however photographers would hate this! So don't see this happening). But the first two of 60fps 4K and 10bit internal are all a GH5 really needs to make a hit on their hands!

What's the point? It's not like APS-C wasn't around when Panasonic and Olympus made the conscious choice to build a smaller sensor camera system. They did that so they could carve out a niche for themselves making smaller bodies and lenses for people that might like that. Now you want them to essentially conform to APS-C. Why should Panasonic build a camera that basically tells people to use third party lenses if they want the best quality out of that camera? That doesn't make much sense for them or most people who buy m43 cameras. I mean if the camera had an APS-C sensor at 24 megapixels and people using Panasonic lenses could only get say 18MP photos (or whatever the m43 crop resulted in) that kind of looks bad for Panasonic. People would be like "what do you mean I have to buy Canon lenses and an adapter to get the full resolution my camera advertises and even then it may not autofocus as well?" It's silly when you really think about it.

If you want APS-C, then buy into a different camera system. Plenty of others offer them. 
Just seems weird to ask Panasonic to change their sensor size when you could just buy a Sony or a Canon or a Nikon and demand from them the features you want. Out of all of those, go to Nikon because they don't have eighteen plus thousand dollar cinema cameras they would have to risk cannibalizing by loading up a DSLR with cinema features. Panasonic, like Sony and Canon, do.

Plus if Panasonic can offer a 20MP sensor for stills (which we know they can) that's a perfectly great resolution. Heck the 1D XmkII shoots at 20 megapixel and the Canon 5D is around that. If they can then do a full sensor width readout of a 16:9 area and produce 4K video downsampled in camera from that, great. If Sony and Samsung can, Panasonic shouldn't be far behind. If they can increase dynamic range and offer a global shutter and compressed raw recording, even better. There are plenty of ways for them to improve without increasing sensor size.  

No, no, no. I don't want a Super 35 sensor in a GH5. I REALY LIKE the Micro 4/3 size sensor. It makes focusing easier than S35, yet still has enough shallow depth of field to look cinematic. I don't care for Speedboosters. I love using my Voigtlander and Lumix lenses on my GH4, and would want the GH5 to shoot on a 5K or 6K m4/3 sensor downsampled to 4K in camera. 10-bit 4:2:2 internal 4K would be an incredible way for the GH5 to separate itself from everything else in the market.
I don't want to use S35 or FF lenses. I WANT my lenses to remain small. I want my whole kit to remain small. There are tons of other cameras out there right now that use S35 or FF sensors. I don't want to pay for a large sensor if I'm just going to use a 4K crop from it because of all my m4/3 lenses. If you want S35 or FF, buy a different camera. Get the Sony A6300 or something else. Leave the GH series Micro 4/3 sensor, because there are a lot of us that find it the perfect size sensor.
 
What I want in a GH5 (in order of importance to me):
Micro 4/3 sensor Internal 10-bit 4:2:2 4K ISO 3200 as good as the current ISO 800 of the GH4 4K 60p No lag on the HDMI output V-Log included Keep the same style body & battery so all GH4 accessories work

NO, I wold not like an APS-C sensor on Gh5!
A multi aspect m4/3  24 MP sensor with 6K video recording, 4K downsampeld from 6K, 10 bit and 4:2:2 internal recording, better AF (especially for video), a better audio DAC, Vlog 2, 60p 4K, better DR and Low light capabilities and a better body would do the trick at 1799$ for me.

@k-robert Don't worry, Panasonic will not move away from M43 for it's still camera line (and that is what the GH series is). I wouldn't be surprised to see them release a -$10k S35 camcorder though...
As far as your desire for more DR and better low light capability, there will be incremental improvements but a M43 camera will never match the performance of a FF camera (all other factors being equal). It's simply a matter of physics- the FF sensor just has more surface are to collect photons than a M43 sensor does. I wouldn't expect A7S ii performance from a M43 camera anytime soon. Maybe when the "organic" sensor is released...

I got this info from a guy who just tested the 4K video capabilities of the camera:
"It records all formats to CF card also. I tested it today.
The 60fps @ 4K would bog down my card after about 10 seconds. But I think if my CF was just a little bit faster is would be able to hang. the 24fps and 30fps @ 4k will shoot forever. It’s awesome."
So the expensive Cfast cards are only needed for 4K 60p.
