While I'm sure that there is some engineering involved to make the SR mechanisms handle a larger full frame sensor, in practice the software change should be rather trivial. Due to the 1.5x FOV factor being done away with, all one would have to do is a mathematical change in the focal length that is displayed on the LCD. (What was formerly a 75mm would become a 50mm). The "problem" is that I don't think there WAS a 75mm (it was 85mm) but my point is (hopefully) taken. The algorithm probably needs few changes but the display focal lengths would.
I think the bigger problem is in the processing engine and the number of AF points. If you are coming from Pentax's AFS-C design perspective to full frame, I would leave the 11 AF points where they are and then design more around the periphery (of the larger sensor). Adding a minimum of 12 might do it, but you have a lot of computational changes to make to accommodate them. In addition, you have a larger filesize to process and write to disk (new territory for Pentax) so the buffer might again be a problem for continuous shooting. I think that Pentax should probably not shoot for PRO land here, but ENTHUSIAST land in their first full frame DSLR. Then take the lessons learned and apply them to the next generation. I think that the body will have to be somewhat bigger, just to accommodate the larger mirror/pentaprism needed for a full frame. It wouldn't bother me if they ignored video COMPLETELY on a full frame camera, but I doubt that the marketing department would be very excited about that. I'm not sure that anyone who isn't familiar with the injection molding (plastics) business can truly appreciate the amount of time and complexity that goes into a significant new revision (like a full frame camera would entail). My employers own three injection molding plants and an injection mold machining business. That's (probably) why the past several models have all pretty much been in the same K-5 body. A full frame would be a BIG departure from that. And that isn't even considering the software side of things. There are reasons that things take time.
