I think there should be an official tournament every 3 months, the winner gets some kind of award or recognition! If Chewbacca Would allow me, I would lead the Wii U tournament separately, or the 3DS one. I can tell you I was one of the best players since the gamecube! I'm so excited!
PS: The official tournament (outside forums) will be held by Nintendo oct. 4 in 12 gamestop stores around the US, the winners get a chance for the final round. My local Gamestop is one of them!
