Heh, you guys are quick to get after me!
YES, movie is important to me....however, I didn't get into film making until about 6 months ago. With that said, I wasn't ready to drop my k20d for a k-7 with the assumption that they would be releasing a 1080p product to compete with Canon.
Frame rate control is also AMAZINGLY better than converting fps. Shooting native 24p vs. 30p and converting to 24p will save hours-literally.
I travel developing countries so carrying a "one-size-fits-all" solution, IE VDSLR, is really important. I don't have the money for a 5dmkII and I'd really like something a little smaller.
I went Pentax because of their legacy glass and unrivaled build quality. Really, I think a k100d feels more "solid" than a 50d, hands down. I really can't stand the UI and button layout of the other companies either. But, at the end of the day, the end product is what's trying to be achieved-HD video.
While 1080p isn't a MUST, I will bet good money that all of HD will be heading that way as a "standard" HD resolution and that's why I the next DSLR I buy will be 1080....and mic jack, of course.
