Thanks, ogl.
I'm not sure how non-committal they actually are. While reading the interview one could believe Pentax is doing nothing but "thinking" and "investigating" potential products; yet we know that's far from being true: they are working, hard.
By the way, AFAIR they never said "no" about a "full frame" camera; it was always something like "right now there are other priorities" (e.g. the 645D) or "we'll think about it, if the market conditions will be right". Now they are "investigating", which is a step forward
(I wouldn't hold my breath, though).
At least, I would say that if those predictions about the "full frame" getting so much cheaper and taking over the world would become reality, Pentax will be there. I wouldn't hold my breath for that, either
