well, I would not mind even less than 18 MP, but would certainly prefer a new sensor (not the same as in 7d, 550d, 600d, 60d).
if the rumor is becoming true, it seems finally the AF sys is coming down again after the 30d (into 400d); 40d AF in the 650d then? so the 70d should get the one from the 7d.. and digic 5 of course.
what about the 240fps video in the S100? why is it not in the 5D3 and not rumored for 650d?
I would be interested in integrated wifi though (to share quickly and easily).
oh yes, and a bigger viewfinder would be always welcome.
