For action photography, the canon 60D a good camera, my 20D took great images (shutter just packed up), the 60s auto focus system not on par with the 7D, just the same as the 1D knocks the socks off the 7D (auto focus), however if you don't use it as a machine gun (fps), rather compose your shots then technique should overcome any limitations.
The only downside with the newer camera's is, you need better quality lenses to resolve the larger number of mp's manufactures are squeezing onto their sensors. The 300mm f4 would be a good partner for your 60D
