Sure it would be lovely to use FA77 on fullframe but you can't use the FA77 on nikon so it doesn't matter much.
True but no one wants to find they've got stuck in a format which has become a poor relation and generally taken downmarket so that quality components for it are no longer available - say, three years down the line. The user base on APS-C is vast, of course, but then once upon a time that was true of film cameras. If the industry as a whole decides to go for FF - for financial reasons - then eventually users won't have much choice anyway. It will be FF or something below where APS-C now is. Say I jump ship now for Nikon. If I choose lenses carefully, I can place myself for APS-C on a D400 or FF on a D600 depending on what pans out with a single suite of lenses bar only one: a 24mm or wider (on APS-C). It is currently much, much harder to do that on Pentax except by forking out for the very expensive FA "three amigo" lenses and there is no really wide FF-capable prime at all.
Looking down the line, I feel this is a potential problem for Pentax. unlike Nikon, they haven't spent 2-3 years planning for a major market change and quietly lining up a range of affordable FF lenses - or so it appears. We can't be sure, of course. The next 12-18 months will be crucial for Pentax, imho, a period when they were able to cement their place as a credible, vibrant #3 or blew it and become just another another-ran as the market changed. Which is why the current affair over pricing is unfortunate, perhaps. Not the best moment to upset your retailers and customers generally.
As everything else on here, just unsubstantiated opinion. I might leave Pentax, though, if poor Mr Bunnell is found to have hatched a plot to kidnap the Muppets and sell them into slavery. He seems to have been accused of just about everything else.
