It's all just blind speculation at the minute and I don't think anyone is any closer to knowing the spec than they were 12 months ago.
I still believe that there are going to be 2 new FF bodies, maybe not both at photokina but certainly in the enxt 6 months, a 6/7/5DII and a 3D.
The only two things that we can be certain of are that they're going to be full frame and they are going to have more than 12MP.
yeah its all guess work but a lot of it by people in the know
I would think the sensor will definitely have more than 12mp and probably more than the 15mp of the 50d
I`m hoping that the sensor/software has the pixel binning tech to get excellent noise control at high iso albeit at the cost of resolution- not a problem if you dont intend to use them for huge prints
its certainly an exciting time for photographers with so much competition going on
