Wow, they're really milking the 18mp sensor huh ?
This rumor proves the contrary - Canon will release the 70d this year with the updated 18mp sensor (i.e. with af pixels for lv, better noise pattern, less banding) and throw everything they have at it like gps & wifi, improved af/fps (but below current 7d).
But even Canon seems to think that they cannot get away with a 7d2 w/o significant sensor improvement, and since they don't have this sensor atm (proof: 6d) they'll delay another year.
