The 7D has the advantage that all its focus points are cross type, too. In truth I don't think there's much practical difference between the 7D and D300s in use. I bought one a few weeks ago for sports and wildlife photography, and have been mightily impressed with its overall performance. One thing you do have to do with it, though, is spend some time learning how the AF works and how to set it up to best cope with your shooting style and lenses - manually selecting focus points in high-speed use isn't recommended! It's time well spent. It also produces great all-round results for general photography, although it's a bit of a shock to have to go back to sharpening everything after using a 5D II for a year, but that's another story.
