Who wants a 7D mk2 and not a FF 5Dmk3 with more dynamic range?
Who wants a FF 5D Mark III and not a 7D Mark II?
At present it looks like the market can have both.
It's a very simple-minded thing to believe that the announcement of a 7D successor would stop a 5D successor - they've coexisted up to now and neither "steps on the other's toes." If anything, we're pulling for the 5D to have better AF capability - the 7D is a godsend because it has a superior AF system at an inferior price
Would a 21Mpixel 7D with more dynamic range from a better sensor and digic 5 be worthwhile.
Worthwhile compared to what? At what price? It won't replace the 5D, so you can stop worrying already.
New is good, but why would i upgrade from a 60D?
Why should we care what would make you upgrade from your 60D?
I'm still not convinced. I'm sure they care just enough to not have their customer's running to another company.
Ditching EF-S support would make that a lot easier for many users.
For me personally, EF-S is almost a non-issue since I have no EF-S lenses - however, messing with the crop factor would be a big problem.
