You're missing the point of the thread very badly here and just coming off as a very rude person looking to pick a fight.
Yes, the 645D is a fantastic Medium Format camera. Yes, the Medium Format has its advantages over Full Frame.
But we're discussing the benefits of Full Frame and talking about "How to push the FF idea more" and not "What's better than the FF?"
Your statement "If you want FF, buy 645D" implies a few things:
1. Buying 645D would encourage Pentax to develop and release an FF camera, which is unlikely.
2. FF is irrelevant and MF is the way to go, which is much like saying APS-C or M4/3 is irrelevant, which is untrue. They have their advantages and disadvantages, and none of those markets have yet to die - which says something.
The 645D wasn't Pentax's answer to Canon or Nikon. They don't compete on the Medium Format arena. And saying that there's no estate to expand, unless you've good information to back that, I'm skeptical to say the least.
Your argument about bigger sensors are the same as APS-C vs MF vs FF vs M4/3.
If a person has a M4/3 lens he'd have to reinvest on entirely new set of lenses for APS-C as well. And so on so forth. Saying that an MF lens, because it has a larger image circle and can theoretically be mounted on smaller sensors, is the absolute be-all-end-all is just preposterous.
