Seriously, given the K-7 and refreshed K-x, the next move from Pentax is a refreshed K20D, perhaps called K-30 or K-z... I'm assuming we are ignoring the 654D from this discussion of course since that was announced for 2010.
The K20D successor probably won't have a 100% viewfinder as I would want it too, just to keep it away from the K-7 market. It will probably get an upgraded sensor and faster drive, based on whatever Sony is cooking right now, which I assume is a 19-24 MP APS sensor to beat Canon at the numbers game but not reach full-frame numbers yet. It would need at least 5 FPS to stay ahead of the K-x.
The other option they have is to reduce the megapixel count with something really special like a ultra-high ISO sensor using black-silicon or extra-terrestrial meteor rocks
