From someone who knows, let me say that you can't effectively use a 60D for sports. You could set it someplace ahead of the action and perhaps get one frame if you practiced. That's if you were lucky.
I respectfully disagree with this, I have a 60D and I've shot many football and hockey games, also people running and never had a problem with the autofocus even in very poorly light environments.. I simply don't understand why you say that. Ok you have the 1dx but don't compare apples and oranges.. 7d is better for sports indeed, but if you master your camera, you do get the shots when it count. 60D is a great camera but for now I would wait to buy a new aps-c camera..
