Parts of Ogl's first post makes sense actually. I won't speculate in how reliable it is though. Here is my own speculations. I have NO insight what so ever. Very few has, and I guess that the few with information keeps it to them selves.
First point; A new aps-c camera above K-7. Yes, why not. If Hoya has put in the cash to make Pentax a brand to count on in the future a lot of R&D is needed. Imo, the best place to put the newly obtained results are in a comparably high spec camera and from there let it spill into the lower series. K-7 is not ground breaking performance wize, but delivers what's expected in its class and does it in a unique package.
If much R&D is done, I'm sure that the findings and ambition does not stop at a semi-pro level.
One year from now, the K-7 is old and gets a "Super" suffix, becoming the middle camera.
Point 2 needs no comment.
Point 3; The FF can also be instead of the upper spec. camera in the first point. I have little belief that Pentax can put too many models out on the market. Sure the big boys can, but having a 5% market share is not easy if not pumping in money like Sony.
The lens designers must have something to do. I don't think that they all are working on WR'ing the current 17-70 and 55-300. Nor do I think that they are all occupied with a few 645D-lenses.
Point 4; A micro format camera. I'm sure they are looking at it. But I guess Pentax won't be even close to pioneering such format until they see how the Pana/Oly offerings makes it on the market.
