To answer the question, my view is that Movie in DSLR is NOT important. If I need it I might as well get a dedicated movie camera that's best it its class.
I think it'll be dangerous waters to thread for DSLR manufacturers to incorporate movie function. Yes, of course technically it is possible. To squeeze such features into a DSLR, it also means that something has to be compromised; and maybe to the extent that the "stability" of the firm ware might be an issue. Like in all things, I'm sure the manufacturers will sort it out in face of competition and when technology improves.
Also, I think it is also silly to be all things to everyone...
Maybe, maybe one day (...my crystal ball says that give or take 5 years time...) DSLRs will be equipped with not just movie mode, but with mp3 player, voice recording function, wi-fi connection, GPS features, direct Internet upload to networking sites,...etc! LoL
Whether it is "Wow" or "yuckky" it's really got to do with what consumers want at the end of the day with a DSLR...As for me, I'll just stick to the plain old still photography thingy and learn to shoot before I can "fly".
