Canon provided cinema5D with a review unit, they didn't necessarily know what was going to be done with it. I don't think many people would buy any stills orientated hybrid for serious long form video work, the video market is overflowing with cameras much better suited to his particular task and I do not think what he was doing is Canon's idea of a general user case use.
I might be labeled a fanboy, which is kinda funny because half the time I'm attacked by them, but I just don't see his use as typical, heck there are countless posters who say they have never used the video on cameras they have owned for years. I believe we are at a point where video centric users are going to have to make serious decisions on what they want and how much they are going to pay for it. To me it sounds like a photographer moaning that paint brushes don't do the job they need, well that's because they aren't the tool for the job. Yes Canon sell it as a hybrid, but it is a photo centric hybrid and a compromised video tool so as a videographer either accept those compromises or buy something else.
