I doubt the K5-level aps-c DSLR would lose any features, though, in that scenario. The 7D and D300s are incredible, feature-rich top-end aps-c DSLRs.
Since Pentax probably wouldn't have an FF offering at the 1DS / D4 level (a $5000 - $8000 body,) it could unload all the 'very top' features, AF, etc at the K1 (5DII/D700) level, something that might give it a slight advantage over CaNikon there.
As far as the lenses go, it's hard to imagine that many aps-c shooters wouldn't welcome a new, 3-lens-per-year lens roadmap, with exciting new K-mount lenses that work perfectly well on their aps-c bodies...
