My guess is:
APS-C cameras (7D2, T4i, 70D) get a 24MP sensor with minor other changes. T4i will arrive in February, the 7D2 later
-> A new Rebel is announced every year, and last year was the first time they haven't changed the sensor.
-> No clue about the 7D product cycle, probably 3 years as the 5D had
The 5D3 will get a >30MP sensor and some other improvements like AF and weather sealing. Announced in September
-> The 5D2 targets studio and landscape photographers, and most of them would like more MP
A new 18MP FF EVIL
I haven't heard much about a EVIL rumor in the last time, but I still believe in it. In the mean time the market is flooded with them and pretty much all sensor sized are available, except an affordable full frame camera. For lots of people their camera is a status symbol, and this would be the top of it. Besides that it would take great pictures ;-)
