What kills APS-H for me is that there are no wide angle lenses for it that aren't curved surface front elements. (Wide angle would require either the 8-15 fish eye or something like the rumored 14-24.)
The 16-35 becomes a 21-45 (for example).
For APS-C, there are lenses like the 10-20.
The APS-H sensor/cameras are designed especially for wildlife/sports. A very small number of wildlife/sports photographers want/need a ultra wide lens on APS-H.
Doesn't Canon want all of those people buying the 1DX instead?
Seriously, the 1DX with its new autofocus sounds like the ultimate camera for sports and wildlife. Well, that is currently available.
It's not like a 7D successor is going to get the autofocus capability of the 1DX and it is the autofocus ability of a camera that makes or breaks it with respect to sports and to a lesser extent wildlife.
The only reason I could see Canon getting serious about a successor to the 7D is if Nikon bring out a D400 that beats whatever the 70D has to offer in a way that requires a new camera from Canon.
Who knows maybe we will see a ultra wide EF affordable lens with the 7D2 announcement.
You mean like the already rumored 14-24? As I said above, that has a curved front element and is not suitable for use with filters.
To be honest how many of us will need a wider lens than 16-35/17-40 on a sports/wildlife designed camera???
And everyone that buys this camera is only going to use it for that purpose, right?
If the rumor is true 7D2 will be a market killer and no need for a entry lvl FF body.
Except for all of those people that own a 5D Mark II and see no point in the 5D Mark III (for whatever reason) and have no wish to ever use a crop camera again.
