Here is a thought. Should HoyaTax indeed come out with a FF camera, and hey why not as prices for sensors drop every year unless ya want the newest sensors. Anyway, something Pentax will have problems providing is long glass as well as solid pro-caliber zooms. A refresher on the FF ability might start here:

Pentax needs lenses to adapt for the FF 1.0x factor in order to provide a full pro line solution. I would think the would want to release a few lenses first, maybe just enough that are FF friendly to imply something is on the pipeline. And FF shooters are going to want SDM and read SDM with quiet ring motors. It's just sort of the finishing touches sort of things.
But if they don't have enough lenses and release a FF body first, then lemme tell ya, the current userbase will be the beta testers for HoyaTax as they shake out the bugs on within the Black Amex crowd. But for real then the longest glass will be 300mm, the only the DA*300 & the 60-250 plus the FA's are FF friendly right? Or am I mis-remembering that part? Of it's not the case then there is a ton of work and resources needing to be devoted to develop the lenses and the bodies. Unless they have been working on this for a few years already and can hit the ground running and release bits in stages across a year's time...I don't see the point.
Yeah, a HoyaTax FF option would be interesting for sure...not sure it's for me though. But it would make a lot of folks happy. I hope there are 2-3 more DFA WR lenses this next week, that could bode well for a FF??? But will these new DFA lenses have trustworthy SDM with ring motors? The screw dirve if fine but for modern day use, it is just too noisy. I mean what good is the super quiet shutter of the K7 when paired with a screw drive FA Limited? I guess about as good as weather sealing in the K7 combined with the same FA Limiteds....
