Honestly, I believe video in DSLRs is here to stay and that more and more publishers/people are going to be not just wanting it, but expecting it. I personally don't understand why there's so much resistance to it, but that's just me

I see a couple of problems with it...
At the moment, video in DSLR's is a bit of a "kludge", an add-on product that works, but has limitations. For example, the auto-focus on some cameras doesn't work in video mode once you start recording. There are also limits on the amount of time you can record, and battery life.
Most folks who shoot high end DSLRs are picky about their photography. If they weren't, they'd be using a point and shoot instead. So these limitations can be frustrating to them.
Others folks, including myself at the moment, don't want to shoot video. That being the case, I'd rather not pay for something I'm not going to use. Also, I don't know if the video functions have any negative impact on my still photographs. I want those to be the best quality possible, and I don't want anything that is going to take away from that.
Meanwhile, if I do want to shoot video, I'll go buy a dedicated video camera. They're specifically designed for video, and at least for now, they have features and functions you don't get in DSLR videocams.
I expect this will change before too long. Maybe the two will merge into one body that can do both, and shoot HDR in hi-res 3D too, I don't know. We'll see what happens.
