Not to be argumentative, but I'll be argumentative. APS-c is not a stop gap to anything. There is no magic to FF other than a generation of glass optimized for it- an ancient generation at that. My first camera used 120 film. Using the FF logic on this thread, THAT's what you should be demanding from Pentax. There is nothing wrong with the IQ from a K-5 and a decent DA lens.
Now I would LIKE to get more from my old Pentax glass. What I NEED is better and faster AF. Low light (high aperture) AF currently stinks. I bring a high power flashlight to my outdoor model shoots, just so I can focus. I don't care how Pentax does it (CD, PD, mirrorless) but the K-5 doesn't hit the mark let alone lead the industry.
I NEED a useful flash system, and Pentax NEEDS to market flashes that compete with much better flash systems from Canikon.
I NEED much less noise in my images. I make promotional photographs for live theatre productions. These are shot in TAv mode (actors move so 1/60 is about as slow as I can go, and I have to dedicate aperture to control depth of field; that is I can't just shoot wide open). So when the only alternative is to shoot above ISO 800 Pentax stinks again.
To wrap up this diatribe - and to address the issue of various camps mentioned before, lack of FF won't make me jump ship. Wasting R&D time and money to make a FF body instead of fixing these real problems is far more likely to cause me and my camp (if I have one) to jump ship.
