Almost certainly. The K mount was designed as a full frame mount.
A few years ago I came up with a list of off-the-shelf FF lenses, and there were about 40 from various manufacturers. I think that's down a bit now, though. It was about 10 from Pentax.
Not all of the K-mount lenses would work - for instance, the 15mm would physically fit, and almost certainly would take a picture, but there would be black areas at the corner where the lens didn't project an image.
In practice, all of the primes greater than 35mm would work, and also the 31mm and 35mm F/2.4. None of the zooms have full coverage although the 60-250 comes close.

Originally posted by Michael Piziak I thought so too. On another forum someone said, " It would be an astonishing event if Pentax suddenly announced a FF camera and a range of lenses to support it." That confused me.
They have more lenses now than any new mount is ever released with.
Guarantee: When they release a full frame camera, they will release a normal zoom.
Likely: Perhaps a telephoto zoom.
Guess: They will say another normal zoom is on the way (faster or slower, depending) and a wide angle zoom + prime are on the way.
