* AF tracking in live view? Come on, that has to be a joke - unless this a completely other design the af pixels on the sensor only tell the camera which way to contrast af.
FTFA: "On chip phase detect pixels for liveview and AF tracking"
Of course it is a complete redesign; this is phase-detection AF (how the lens diverges the light, and fast because the camera "knows" which way to focus depending on how the light waves have diverged) rather than contrast detection (which is slow because complex algorithms have to figure out when the image is sharpest and the camera can't know which way the light has diverged). In order to integrate phase detection, unless they're being really clever with the use of photosites' data and taking the color shift of the bayer filter into account, the sensor will have specialized "pixels" to dedicate to focus. It would be similar to the normal phase detect AF sensor already in every Canon DSLR, except miniaturized and integrated into the image sensor. Based on TFA, we can assume that they are integrating miniaturized phase-detect pixels directly into the sensor.
This will be a
huge win for videographers, especially with the release of more and more STM lenses. The 7D can AF during video recording, but thanks to contrast detect it is slow since the camera has to "guess" which way to move the lens, and how far it should move. With phase detect AF (assuming sufficient light for phase detection to work) it knows pretty precisely which direction the lens needs to move, and by how much.
* GPS/WiFi - so we can expect the camera to miss the external flash (that's where the antennas are) and you have to buy a €300 or €500 (with af assist) piece of equipment just to control off-camera flash just like the 6d? That's probably also the reason why there still is no built-in rt controller even in these 7d2 specs... thanks. Canon.
WiFi? Meh. See:

21MP APS-C? The 5D3 at ISO 102K is pretty noisy. I can just imagine what this will be like at that ISO.

If DR improvement is not mentioned it won't happen, so we shouldn't expect it or speculate about it. Same sensor as the 650D but smaller (more noisy) pixels, faster readout, better AF and Body. I'd call this camera a 6.5D.
SRSLY?
It's not like they take the exact design they had before, shrink it down, and then add a few pixels around the edges to increase the resolution.
IF that was how they made higher resolution sensors, you'd be right. Compare today's 18MP sensor to the D2000/DCS520's 2.0MP sensor at ISO 12,800. Oh right, today's 18MP sensor is more usable at its expanded ISO than yesterday's 2.0MP sensor is at ISO 800.

Plus 1 too... The 7DII needs to be more than this, fine with resolution stated, fine also with wifi and gps built in (easy extra sales point = higher price = higher profit margin = keep selling cameras) the AF needs to be top notch for crop at 40+ points, otherwise, the real game changer can only by the performance of the sensor which in my opinion, needs to outperform the lesser crop models, not recycle the same tech.
Are you willing to pay the price of the old APS-H model for the 7D? I ask, because that is the level of functionality that many in here seem to be demanding.

AF point count? Mexapixels? How about the fact that the 7D dedicates a processor to AF, and that it has ALL cross-type points with a high-precision center point, which is better than Nikon's system? What about durability and weather sealing? Tendency toward excessively high Moire (no low-pass filter)?
What about ergonomics? Still is lacking on Nikon.
What about the fact that when the megapixel race was going on, people were slamming both companies for increasing resolution?
The truth is, people love to whine regardless of whether Canon moves to increase or decrease resolution, increase AF point count or decrease it, and hell, some people even complain that they don't want to pay for video features or for fast burst mode. For those folk, rather than buying the more appropriate Rebel or "super rebel" XXD, they whine and moan about the pro features the 7D has. The thing is, the pro features that make up an XD model isn't rooted in megapixel count, whether or not it includes wifi, or number of AF points. It comes down to image quality, ergonomics, durability, and a mix of all of the features offered by that particular camera body.
Wait for the D400. It might be superior, if this 7D specs are true. And the D400 will be - again - cheaper....
Canon, hurry up and make it better!
Eventually Nikon will come out with something better (then certain people will threaten to jump ship to Nikon), then Canon will leapfrog them again, and people will threaten to leave Nikon for Canon. Those people blow lots of money on gear just for bragging rights, but don't even know why the gear is designed the way it is. That's fine and all (your early-adopter gadget freak mentality in essence subsidizes my gear purchase thanks to the economies of scale!!
) but unfortunately that vocal few is the people who flood forums here and dpreview with all of the negativity.
maybe will be a faster AF ( due to the DIGIC 5 processors... I personally prefer a strong 19 AF point instead of a crippled 51 AF.
