Forget this "partial frame" / "full frame" claptrap. The camera that would accept the 645/67 lenses would have a sensor at least as large as the sensor in any K-mount body. Not only that - the increased register distance (or, to be strictly accurate, the increase in distance from the film plane to the rear nodal point of the lens) means the camera would be less likely to exhibit chromatic aberration with wide-angle lenses. The people who would buy an MF-based DSLR are principally those people who already have a sizeable investment in Pentax MF glass. That's the one segment of the pro market where Pentax have been successful - they need to do something to protect their market.
