The 60D is an underrated, but for sports and action, the 7D is cream of crop sensor bodies. Many point to the 8fps. While this has it's benefits, the real action advantage is with focus lock speed, focus tracking, 19 cross type focus points, and the expanded, movable single point focusing. The expanded focus point improves servo tracking and the ability to move it quickly simplifies the framing of your subjects.
I have both bodies and love the 60D for short zoom work where the flippy screen is sometimes used. But, the 7D is my primary camera for all things action – including some candids where you want the camera to lock in on your subject before the moment is lost.
I shoot a lot of figure skating. With my 60D, my in-focus success rate was about 80%. It often had a little trouble tracking skaters when they changed direction, even with the 70-200 f2.8L II. With the 7D, the success rate went up to 95%. The focusing is that much better. Remember, the 7D has two processors, one dedicated to focusing. (The 70-200 f2.8L UMS IS II is also a stellar focus performer.)
I bought 7D through Canon's refurb store and would highly recommend that route. As was mentioned in a previous post, it could be many months before the 7D2 is available. If you wait, that lots of pics you'll miss.
