Nikon D7000 for Sports and Fast moving objects

I currently have a Nikon D3100. Im thinking of upgrading to a Nikon D7000. I used it over the weekend at the SGP F1 and really impressed with its picture quality and speed.

But i wanted to know over a longer term period, is the nikon a good performing when it comes to sports and fast moving objects with its AF points and 6fps. The reason why i ask is i want that in my camera for when i go to the f1 and i read mixed reviews of it against the Canon 7D. I hear the AF points are better on the d7000 - and better at focusing on moving objects but the burst rate can be lagging compare to 7D.

Any thoughts? Otherwise i'm won over by the d7000.
