Come on, K mount compatibility is one of the very few Pentax trumps, and they need to play them all. Even if few posses both old lenses and new equipment Pentax still has to proclaim loud and clear "our dslr takes whatever glass caries the Pentax name!".
Until they come up with serious technological propositions like IS/USM that really tempt the users to buy new lenses, abandoning full K mount compatibility is not an option. BTW, I think you're wrong about the numbers. There are millions of K/M lenses out there and if only 1% (and that's very conservative) end up in the hands of enthusiasts, then Pentax should pay very close attention to satisfying this market segment.
