Another Canon or Nikon?

For me this it's the year for camera upgrades, since the new year I am looking to buy my third and final camera. I am comparing the Canon 7D and Nikon D7000 (I use both systems), the 7D has 18mp, two more than the D7000 and 8fps compared to 6fps, apart from that I don't see much difference except that the 7D body costs $1,600 and the D7000 $900, am I missing something? I'd be happy to hear your thoughts.
