Canon 5Ds and 7Ds shoot in 1080p... why would you go to 720p... ever? I have NEVER had a client request 720p. It's either SD or HD, and HD meaning 1980p... the client wants it the best delivery method possible, and currently that is Blu-Ray 1080p.
720/60p. There's your reason. 1080/24p looks like crap when anything moves quickly with sports and motorsports. For weddings... sure. Weddings dont pay my bills though, sports videography is what does.
Just FYI - there is no television station that actually broadcasts 1080p. ESPN and Nat Geo do 1080i in certain scenarios, but not even an HD channel is 1080p, ever. Since I do video for web and the air... 720p is the standard operating format for anything short of ESPN. I sent them 720p footage the other day and they had no problems with it...
