I'm not sure Sony 20MP sensor has the performance needed for a high end DSLR.
Cameras using it has 5 FPS or lower frame rate and 1080i video mode.
Frame rate on Sony A58 is 5 FPS, and went down from 10 FPS in A57.
Sony probably is going to replace quite a few cameras in the near future so it might not mean all that much if Pentax K-3 is out a few weeks earlier.
Sony A77, A65 and Nex7 are all over 2 years old, using the old 24MP sensor, and will probably be replaced soon, but Sony might have other new APS-C sensors coming with more than 24MP that they prefer to use in these cameras.
