Worldwide Wii will probably surprass the 360 this year. In the US it's going to be a while longer, if ever. Halo 3 will sell the 360 to a lot of US gamers. In Europe and of course Japan the 360 has no chance against the Wii, but they do have some shot in the US. However I think it's only a matter of time before the Wii is the leading console in all major markets. Long term I think the PS3 wins overall, though that's a topic for a different time.
