P.J. is right, at least in my case. If/when Pentax introduces a full frame DSLR, I will probably buy one (eventually) but I won't be one of the first in line. A full frame sensor, by itself doesn't really gain you anything except: 1) shallower DOF (at the same focal length, compared to a APS-C) 2) losing the crop factor (meaning your 15mm is a 15mm FOV instead of a 22mm FOV) - helpful at the wide angle end and for tilt-shift lens users. 3) more megapixels (potentially significant depending upon the pixel pitch) 4) if a larger pixel pitch, then potentially better noise performance at equivalent ISOs
The downsides: It depends upon what sort of shooting you do, but a larger filesize is probably going to mean lower frames per second on burst performance for action shooting, compared to a APS-C camera. Fewer frames until your buffer is full and has to wait to take another shot. Larger filesizes means more computing power to post-process and store images (something we seem willing to live with). Macro shooters will find thinner DOF to be a disadvantage, rather than an advantage Full frame DSLRs will really show the deficiencies in your lenses, particularly in the corners. That said, Pentax probably needs to produce a full frame DSLR, just to show they belong with the "big boys" and prevent some (more) from jumping ship to another brand. For my part, I love wide angle but find that the Sigma EX 10-20mm more than meets my needs on the wide angle end of the spectrum on a APS-C camera. I also love macro, so the increased DOF is a plus on an APS-C. The K-5/K-5 II already leads the pack at high ISO performance and the megapixels already exceeds what I need for the print sizes I will realistically ever print. I can get shallow DOF with my Sigma EX 28mm f1.8, my CZJ 35mm f2.4, and my 85mm f1.5s (heck, the DOF is shallow enough in many cases on my Bigma - why would I want to make it more challenging?) In short, the Pentax flagship cameras meet or exceed my expectations right now and a full frame doesn't do a lot for me other than let me proclaim that I have a full frame camera.
