I can't speak to specific differences, I expect the 60D to be taking a step backwards to a minor degree in build quality. A big advantage that the 7D will provide is anyone taking Sports or Action photos is its 8 fps capabilities. I believe the 60D is shy of 6.
7D also provides 100% coverage through the view finder, where the 60D is only 96%. I suppose the sensor is relatively the same, so what differences there are minor.
The 60D has the new flip out LCD, which I am not impressed with.
When looking at BandH the price difference is more around $600. If your shopping is based on budget then compare the Rebel 2Ti to the 60D. I'm expecting the a replacement for the 7D in not to far future.
I have a 7D and a 1000D as backup. For my work I find the quality of the lens is more important than the type of body. I'd be inclined to get the cheaper body and spend the difference on really good glass.
