What does this mean for the 5D3? Nothing! People who want FF are not going to trade in a 5D3 for a crop camera ....
Also, despite some of the rumors here, I don't think the 7DII will get the 61-point AF system of the 5D3/1DX.
So, the AF system will be another differentiation from the 5DIII.
Btw, for the 7DII AF system I'm expecting either a beefed-up version of the current 19-point AF (e.g. with better sensitivity to low light) or a maybe new AF system, which would still be a step below Canon's pro AF system.
But we are definitely not getting Canon's pro AF system in a $2K camera. That's for sure.
You know Canon .
