I wasn't denying the 7d2 possibility just the specs being a 7d2. These specs make me think of 1dm3 and 1dm4 at $4000 or more. A 7D2 should be around $2500/$3000 in my guestimate.This doesnt seem to be a 7D II concept but a 3D or whatever concept since it would sit between the 1d and the 5d much like the 1dm3 did. Thus Like neuroanatomist mentioned about $4000.
I would expect an excellent game changer 7DII to be $3000. Who nows really, only Canon.
Its nice to see CR posting about focus speeds being related to voltage output, it seems to not be understood by many as the reason why a 5dm3 and 7d can't focus as fast. But then there are also many that do. I am re-stating it to continue the awareness.
whilst I see you point, I think that canon has made the 1-series "universal" in going high-speed and full-frame.
this does leave a gap in the line that can be filled; a cropped sports camera. the 7-series is such a camera
as for the 3-series, that's been desired for years but with little basis in reality. a new 7-series is somewhat more likely
