There won't be an annoucment I was just saying people are pointing to price drops on the 5D Mark II as a sign of replacement coming, but on the same day the price of the 7D dropped so I was being sarcastic being saying that the price drop must imply that a 7D II is coming. we all know it is not.
Actually I think it would be logical for Canon to release 7D2 soon. They are not going to use the same 18mp sensor for the Rebel next year, because the history shows that each of the older Rebels had a different "new" sensor and only 550D and 600D had the same one. So, it may be introduced in their APS-C flagship camera to prevent the 7D line laging behind the competition. Despite that 7D is already a very capable camera, there is a lot to improve - LCD display (3:2 or even vari-angle), multiple memory card slots (CF+SD?), more fps (10?), higher speed flash sync, more processing power (dual Digic5), larger buffer, 1080p 60fps video, better performance sensor (cleaner ISOs and better DR), it may not need a new AF or metering system, but it could be like an improved version (rev.2.0). Maybe Canon decided to update all of their xD bodies (1D, 5D, 7D), what's wrong with that?
