IF the 7D2 has the same sensor as the 70D...
1) Shame on Canon. 7D2 is the standard bearer for APS-C. It must have the best sensor they have. A year old sensor is a weak offering there. I am not saying this for megapixel reasons, but for the fact that a flagship body should have top to bottom new tech at its core.
2) Everything else about this camera had better be gangbusters -- better build, 10-12 FPS (entirely possible with 2014 processing power against only a 20 MP sensor), the 1DX/5D3 AF system, etc.
This was supposed to be a camera costing more than the 6D, the 'pro APS-C rig' for birders and sports guys with huge glass, etc. But for the first major design decision we've heard of, this is a poor way to justify that kind of money.
