I don't think that pentax will go down that route any time soon because... 1. Their current lens lineup and roadmap seem heavily biased towards APS-C If they had FF plans i think they would be releasing FF capable lenses.
2. The technical demands FF makes on optical design make good FF optics expensive and given the small volumes they can sell (compared to C...n) unattractive for the potential buyer. Furthermore the lower volumes will drive the prices even higher. 3. It may hurt the 645D's sales potential IMHO those are probably the most compelling reasons for not going FF i'm sure there are more.
