With my K10/K20 duo working very well for me, I passed over the K-7 and waited for the K-5 to come out, bugs be identified and fixed (more or less) and then bought the K-5. Now after 6 months with the K-5, the K10 has been sold off and the K20 is beginning to gather dust. IMHO the K-5 is a very significant step up from the K20 - much more than even I thought it would be. The K-5 was the one I was waiting for and didn't really know it. Just upgrade!
As far as a Pentax FF camera goes, while it would be nice to have that option but given the likely price of a FF (based on Canon, Nikon, and Sony models), I'm unlikely to be able to justify the expense. If I could, I'd have a nice shiny new Pentax 645D sitting on my table.
