As stated by Popo, Canon will come with a follow up for their highly popular 7D. The MK II is said to go to 10fps, making it a sports camera and possibly an alternative for those who miss the 1.3x crop for the extra reach. It will also offer more features and innovations than merely being a better specced revamp.

 

A Canon representative has hinted at that Canon thinks enthusiast semi pro models will move to FF (6D), but that is about the 60D line, not the 7D which is aimed at more professional use. There still will be a 70D.

 

APS-C has a big plus over FF (more reach with same lens), which still makes them attractive to wildlife/bird photographers (and some sports photographers). FF's only real advantage is a possible more shallow DOF, with a weight and size penalty. That is not going to change, so there will always be a market for higher specced APS-C cameras. It is not just a price thing.

Another plus for APS-C is the ability to use dedicated crop lenses that offer much better across the frame sharpness uniformity - compare for example the Sigma 8-16 and the 12-24 II... the peak resolution in the center looks higher on FF for sure but the corners lag way behind, and you have to stop way down farther than on APS-C to make them sharp (whereas the 8-16 looks sharp all over at wide open in the PZ test). That may somewhat negate the point of FF since you have to jack up the ISO accordingly, which may or may not trump the noise advantage the same generation FF sensors have.
