A couple of the issues are Canon-wide issues, and not specific to the 7D2. They also only shot JPG, but if the JPG is good enough, who cares about raw, that was my take on it. You cannot compare the 7D to the 7D2 via the camera JPG, the newer JPG engine murders the old one. I mean you can compare, if you shoot JPG, but if you like raw comparisons, this review did none of that.
They also poked fun at the desire to view everything at 100%, I found that funny. I also am going to look into Photo Mechanic, it sounded like a great tool for the sports shooter.
The most telling was 2 things from Scott: a) he often forgot he wasn't shooting with the 1DX and b) the high ISO was much better than he would have expected (even though he has a 70D?). He shot a little of everything, he shot a wedding, some landscapes from Maine, and then a couple of big football games. The final assessment really was that "he was expecting that the 7D2 would be the 1DX's little brother, but it is really a more mature teenager brother of the 1DX".
He states too that the 70D is a good all around consumer camera and tells anybody looking for a crop to get the 70D, but the 7D2 is for the sports and wildlife shooters, since it steps up the game quite a bit.
