Falk: But this doesn't mean anything over 1400$ is "FF territory"... to be so, we must have FF cameras there - and I don't see any
"FF territory", for now, is 2000$ and beyond - no matter how cheap the APS-C cameras are. Yes, there is a gap in between (on which no APS-C camera can be sold, even the 7D) - but that's another story.
For now, the most expensive APS-C is 1600$ - street price, with 100$ instant rebate. The D300s is over 1500$ (again, street price); I don't think Canon and Nikon will soon abandon the over 1000$ APS-C DSLR market - an over 500$ drop, no way. And the others... they don't really compete for "the best APS-C DSLR" (best as in: we can ask tons of money on it) market. Sony? Olympus? How old are the A700/E3? Panasonic? Did the had a top-end 4/3 DSLR at all? Samsung has given up, they were only rebranding Pentax cameras, anyway. And Pentax... the K-7, while a very nice camera, is by no means the "best" APS-C camera one can make.
You'll see, the next high-end APS-C DSLR will be well over 1000$, I'm sure of this.
These being said, I would be satisfied with an upgraded K-7 (the K-7 being already a very good camera). I'd also prefer a quieter 5.2 fps shutter/mirror mechanism than a noisier 8fps one; if by any chance Pentax would increase the frame rate, I hope they'll also put a "quiet mode" in there.
