Any chance they put the 5d3 autofocus system in the 7d successor?
The af arrays for full frame and aps-c are quite different, no chance of a straight port from the 5d3.
I don't think Canon's product line will be influenced by what Nikon makes in the short run.
Imho the opposite is true - just with the d600/6d Canon will make sure the d7100 competitor (i.e the 70d) will have at least some appeal, just like the "one good feature" 6d has with the low light af center point.
My point was that in the short run
it may not be possible for Canon to make any substantial modifications to the 7D2 / 70D beyond what it has already planned. If the 7D2/70D were to be announced within 4-6 months, it must be undergoing the final testing and I doubt whether any modification beyond a cosmetic change and/or a gimmick will be possible.
I agree though that the the 7D2/70D will carry a major upgrade from the current 7D. A superb autofocus, 10 fps, better sensor ... the wishlist goes on

When it comes to gear, it is better to vote with your wallet. Bitching on online forums like a lunatic doesn't get you anywhere!
