1. It is unlikely there would be for mirrorless as well, FF or otherwise. The entire concept of the DSLR may be "topping out" as a growth market. FF at 2x the cost of the K-5 is not going to grow any market by definition.
2. Making a $3,000 body for legacy k-mount glass is foolish because that throws all the profit onto the body, not the glass and accessories. The real $$$ in camera systems is the lenses and accessories.
The reality is a k-mount DSLR at FF would be very expensive because the sensors are estimated to be about $800 per unit and the "pro" features that go into the body make it both large and expensive.
To all those who argue for a FF upgrade path because the system 'tops out', but then state that Pentax needs to find its own niche, you're contradicting yourself. If Pentax creates that path at very high cost, they are exactly where Canikon and Sony are with FF sales less than 10% of APS-C sales, less for Sony. If you create the upgrade path you're exactly following in Canikon's shoes, which Sony tried to do but have largely failed at. Pentax has no technical or engineering magic pixie dust to shrink RAW dump RAM and circuits to create a similarly specced pro body with PD AF and in-body SR and make the system smaller as a sales advantage. Historically, in fact, making systems smaller has not worked in SLR land, nor DSLR land. Pentax and Olympus made smaller non-pro systems and the high-end of the market stuck tot he big body Canikon's and Minolta's. It s neither possible to shrink the DSLR FF form factor much below, say, the D300, in size, nor is it a market advantage.
And selling to legacy lens owners is economic suicide. You don't trick out an $800 Sony sensor in a pro DSLR body only to have some guy throw a budget 30 year-old eBay prime on it for his shooting experience. That's not a market. Get real.
