I have to agree. As others are quick to point out, one major obstacle to Pentax releasing a full frame camera is that they've let their line of 35mm glass lapse, particularly in the area of zooms. Basically any time they design a lens they have one of two options, to fill a 36x24 frame, or to only fill a 24x16 frame. Obviously the first option adds unnecessary bulk to the lens
if it will only ever be mounted on an APS-C body (of course it does let APS-C shooters take advantage of the sharpest part of the image circle), but this design philosophy has left Pentax in a position of being unable to offer lenses to go with a full frame DSLR should they choose to release one.
And hey, what about some love for us film shooters? Canon and Nikon never abandoned their film users. I may be wrong, but I believe both companies still make a film body, and of course all their Fx/EF lenses can be used on film.
I view this 70-200 f/2.8, if indeed it ever sees the light of production, as a way of getting back to a path from which Pentax never should have strayed rather than the herald of an imminent full frame. And in keeping with that theme, I hope they include an aperture ring.
