The video that I produced at 1980x1080p, 30fps, looks amazing. (You'll just have to take my word for it for now. I'll be uploading it later). I admire people who are able to produce amazing videos with a DSLR but I can't do it for paying gigs where retakes and reshoots are not available options. For personal, "artsy" projects, yes, I'll use it.
Photo equipment should be such that their operation and use becomes intuitive, an extension of one's brain/hands. I can see myself using a Sony VG10-type of camera for shooting videos: big sensor, workable continuous auto-focus, ideal form factor.
