Will Pentax follow??
No. Or at least not anytime soon unless there is a major surprise in the works. By ending production of virtually all full-frame compatible lenses, Pentax has made a firm commitment to the APS-C image sensor.
Digital photography is a new world, not constrained by the standards of 35mm film cameras. As such, there is no valid reason for Pentax to be constained by that either. If you're going to argue image quality, why stop at a 35mm film size image sensor (so-called, full frame) when an image sensor twice that size might deliver even more? If your answer is compromise, why not compromise with a smaller sensor (APS-C) that delivers nearly equal results while offering lower cost, smaller cameras, and more?
