I just remark that for a few people wanting video implemented on a DSLR, but there's no reason their needs would decide what everybody else should have. So, all DSLR bodies must have now video, even if video pisses off the the majority of the owners forced to buy it when just wanting a still photo camera.
Canon don't care about our preferenecs, just wanting to sell more cameras and lenses, putting video in each one.
I wonder whether it is really just "a few people" who want video implemented in DSLR.
By brother in law and his brother both bought Canon DSLRs (600D & 60D), and video was more important to them than the ability to change lenses. It's arguable whether they should have bought a DSLR to begin with, but as noted - Canon's decision to include video in those cameras increased it's bottom line.
I don't really care for video, as in I have a pocket camera that shoots video anyway. It did come handy when a friend used her connections to get a video clip for her boyfriend's song - she got 2 x 5Dmk2s loaned from me & another friend, two videographers shot the footage, and all the required footage was shot within 1&1/2 work days. It's not Hollywood quality, but for something pulled in a jiffy, I think it's very impressive.
[They've used whatever lenses available, including 50mm f/1.4 for shallow DOF, TS-E 24mm mk2 for wide shots, Sigma 12-24mm mk1 for ultra wide shots, etc.]
I didn't buy a Canon DSLR, nor would I upgrade it, for the video abilities, but it's really nice to have.
