Please note that the dual pixels get their light from different sides of the lens, so the alignment won't be perfect for dual-ISO case. It would be as close as calling it a 60Mpx sensor. What this COULD be used for is:
- Tweaking focus after the shot
- Simulating the use of a smaller aperture after the shot (though to get a good result, you'd need the pixels to be split both horizontally and vertically)
- Stereoscopic imaging through the creation of a depth map from the split-pixel difference information
- Offline AF-MA by going through your RAW files, doing some statistics on difference between PDAF and DPAF values
...and several other processing-intensive things similar to what's being done with the Lytro cameras. If we can get our hands on all the info needed for this in the RAW files, it's gonna open up some really nice new possibilities. It'd also lead to quite a delay before the raw format is properly supported by 3rd-party software (Adobe probably already have devs working on it)

it would be amazing if it read each pixel with some sort of dual ISO in true native fashion (nothing like the ML stuff), like it could read everything say under ISO1600 at both ISO 100,200,400,800 and also at ISO1600 at the same time and then you use the ISO1600 read for clean shadows and use the regular read for all the non-shadow stuff
if it had the on chip ADC of the 1DX2/80D (which are still a good deal worse than Exmor) but also did a dual ISO read of each pixel (at one go) I'd think that might give the best DR we have yet seen along with no negatives
but maybe it means something not quite as amazing, maybe it's just like the ML stuff and it applies every other row in block and has other issues

it depends, if it's really done well and wouldn't have the negatives of what ML does, then it would need to be hardware

USB3.0 terminal, HDMI terminal
size X 116.4Mm X 150.7Mm 75.9Mm

There's still a ton of fine print we don't have yet, but red stuff is surely the secret sauce we've been hearing about. This is what everyone will buzz about until legit marketing collaterals or a manual leaks.
I don't want to speculate that it's referring to Dual ISO (like from Magic Lantern, but optimized, designed expressly to do this, etc.) but someone already beat me to it on another thread. Here's hoping -- that could be wild, gamechanging stuff.

I'm trying to figure out why I'm fairly unimpressed. Hopefully in action the camera will be amazing, as a 5DSr user those specs don't light a fire under my wallet.
It's 60g lighter, which is a big thing to improve but did it cost the Mag Alloy as a result. 7fps but what's the buffer etc.
But it's a start.

Thank-you, I hear far more hate than love (which comes with the territory). Even after this posting, I'm still getting hate emails from other web sites (they think they're incognito).
This was the hardest product to get specifications for ever. I assume it's only going to get more difficult.

Some will never be impressed no matter what the spec maybe. I have mates who are not impressed by the 5D4 spec, they would still not be happy if the camera had pop out legs, walked itself to weddings and shot the whole even by itself hahaha

I'm sure the dual pixel raw (if it really uses the dual pixels and not just performs a normal readout twice) will not be dual ISO. Do you like bokeh discs that are blown in one half and not blown in the other half? Both pixels read with the same ISO would however increase the dynamic range of the raw file slightly, although very inefficiently (double file size for 14->15 bit), just increasing the bits per pixel for the normal raw would be the much better choice for this.
It will likely be more about drawing depth information from the image or confirmation of focus precision.

Great work CRguy. Work like this is like keeping the power grid running. Nobody thanks you for your daily hard work, but just wait to when it's not working - people will go all angry-villager on you with pitchforks and torches.
That being said, I'm getting more and more satisfied by my decision to pick up a lightly used 1DX for sports/action rather than waiting for the 5D4.

Resolution is what I expect from such a camera. Very appreciated. I even would have liked a 32 MP resolution but oh well.
As for video: 4k@30 is a bit of a downer. I expected more (PAL 50 or NTSC 60 frames) from this than just the basics nowadays. I expect HD is 720p@120 and that would be a downer too. Reviews from 1DXII in that area weren't really good (image too soft) and I hoped for an improvement in the 1080p department. We will see if this reads better when the final specs come out. So far I only read about 4:2:2 8 bit output. Not the best either for serious colour grading. I expect the motion jpg codec to be in it as well, possibly up to 500MBit/s, which would stress the card space a lot. A good codec would improve here as well. What about C-Log? Any info on that? The 1DXII is a miss in that region too....
So all in all its a mixed bag so far which brings this camera to at least to "yesterday", in certain areas to the "now", but I am hard pressed to say it brings it to the "future". There is a lot to improved upon judging from the specs.
I have to think hard to upgrade from my Mark III or go elsewere.

I have a friend that bought 2 1DX's for the price of a 1DX2, it's a great camera and is pretty much the best value for a DSLR out there right now on the used market.

Very very Underwhelmed with the specs of 5D4 
I was hoping for at least 36mp with No ALF (variable ALF like rxr2) for sharper images, great low light, DR & some new technology derived from the Mirrorless world....something vow like what 5D2 offered when released.
...How is this camera any better than Sony a7r2 / s2 , Nikon 810 ??? which are at their end life cycles & nearing upgrades themselves.
I don't think I can stick with this 5D4 for the next 4 years. Come on be realistic !! Canon philosophy with the 5D line seems to be 'Let's give them just a little so as not to jeopardize their higher end cameras/cine Line'. Canon is still playing the catch up game.Very soon we'll have the Hasselblad X1 medium format mirrorless, the pentax 645Z2, a7r3,.... coming to market. Way Better Image quality & prices are coming down.
I was waiting to upgrade from the 5D2. As a stills photographer & occasional video (70:30 ratio) ...the 5D3 did not offer much so was waiting for the 5D4...and now....this is not significant motivation enough for me to push the $$'s canon's way....I was sitting on the fence with the sony system with the new awesome GMaster pro & batis ,loxia lenses. Now I would be looking at the SONY a7r2 - a7r3 seriously....the awful battery life on the Sony, a general reluctance to switch & huge canon lens collection is what is holding me back tough....but imho still sticking with 5d4 now when there are so many choices would be a dodo approach...I want the best that's available & pl don't say go buy the 5DSR!! it has many issues & is very niche for my needs.

This is looking more and more interesting. The dual pixel raw files sound interesting, but I think we can trust Canon to underdeliver on its potential. I don't expect any automatic AF tuning, for instance. That would be far to convenient =)
I'm sure the new button on the back is the AF area mode selector, revised from the 7D2. The lever on the 7D2 is a little tiring for the thumb, and a regular button should be easier to use.
I really hope they have made the NFC/Wifi connection process fast and easy to use, once set up. My current setup with an Eyefi mobi pro in my 7D2 is more convenient than other implementations I've tried, the 70D for instance.
