Canon seems to think that many of their users want good video, and sophisticated video functions. Canon has sunk a lot of R&D time,effort, and funds into improving d-slr video. I have a young niece who is now working for a small-market television news department as on-air and field talent...there are quite a few people in the news gathering business using d-slr cameras for video work...there is even a blog devoted to d-slr news shooters....it's called DLS News Shooter.

The nice thing about a Canon EF-mount camera is its easy-peasy adaptability to lenses from seven different lens mounts--lenses that have mechanical aperture rings, for the most part!
As far as the specific 7D versus D7000 comparison--to *me* (and this is just me,and my own personal situation), I like the fit and feel and the viewfinder of the Canon 7D more than the Nikon D7000. For *me*, with *my eyeglasses* and *my vision*, the Canon has the better viewfinder. To *me*, the viewfinder, the eye-level,optical finder, is the critical usability issue. To me, that is the one area where the D7000 loses out to multiple other cameras--the viewfinder system.
