Ever heard of a thing called competition? Pentax will probably HAVE TO follow the nikon/canon model of aps then full size digital sensors in SLRs to stay competitive.
I think it will be possible to compete on the APS size market only, like both Canon and Nikon have competed on the 135 market only.
SLRs will become the pro/advanced amateur market only. They will abandon this market or produce full frame SLR, they really have no choice...
We will probably have a new class full dSLRs having full frame sensors and being aimed at a market corresponding to the medium format today. In addition we will, of course keep the film based medium format systems with digital backs.
Eventually, the only way to effectively increase pixel count will be to make sensor larger. Otherwise the pixels get too small and become insensitive/noisy...
I agree with you there,,,
