Pentax have the mid-level camera to reveal, it was under glass at CES, they might hint at FF coming but I would not expect anything to come of it until at least 12-18months from now if at all, they don't have the lens line up yet, unless they rely on some third paty lenses, there seems to be one from Tamron
http://www.camerasdirect.com.au/tamron-sp-24-70mm-f-2-8-di-vc-usd-for-pentax..._store=default It has VC maybe the FF mythical beast will have SR in lens instead of in body, I'm not sure how old that lens is but seemed to pop up on their list where there wasn't one previously. Pentax might have a 70-200 in the works but they need a stack of prime lenses with HD, maybe they will hint at those this year?
What I would definitely hope to expect is some real information on a K-3 successor, some of the new stuff from the mid-level up-commer and prospective K-3 might make it into the FF dev-branch. Expect nothing and what comes will be a treat
