Video is very important to for film people, who generally don't care about stills, but would love to make use of our awesome glass. It's also important to people who would like to embarrass their kids in 20 years. So there is broad consumer appeal, and a high end niche appeal, we enthusiasts and still photography pros are the one's who are having the hardest time wrapping our heads around it all.
I will say that there is an emerging class of multi-media artists who are utilizing both film and video. I've seen some really impressive stuff. So I wouldn't knock video SLR's. I'm just not ready to start using them... yet.
