This year we will se two new bodies:
3D: High MP (40+), slow FPS...
5Dx: Low MP (22), faster FPS...
That way canon will have a product for both niche markets!
In case of bodies:
1.) I think that there will be one high mpx camera + I assume it will be the 4K with RAW video (which was also patented). It will be low fps, fewer AF points, video and studio focused camera. This could be 4000-4500 USD.
2.) I assume it will be something like posted 5D-X or however it will be called. Light prosumer body with good AF, around 6 fps, +-22 mpx FF sensor, great high ISO and around 3000 USD as price tag goes. This will not be a direct competitor to D800 (fewer mpx, less fps, possibly no RAW video).
3.) I think there will be a Rebel body. Not sure about specs. Maybe they just bump new processor in it and 24 mpx sensor (but currently 18 mpx is enough).
There is, for sure, market for another 2 FF bodies. If they divide them like this, they will definitely profit from this.
