PEOPLE!!! The 360 and even the PS3 is not going anywhere and will not be closing up shop anytime soon. Too many kick ass HDTV's to keep both systems alive. I don't care if the Wii outsold the 360 and PS3 three fold, its not taking out either system. The Wii has its place as a niche console, and not a revolutionary one. Maybe thats why Ninty strayed from the revolution name. Is the Wii a better success than the virtual boy, yes, but it doesn't have the whole package to take out the other consoles. Xbox dropped the ball somewhat and should have had the HD DVD player in the console, but even without that the 360 has some great titles, mainly adult oriented, but great ones indeed.
All the Wii needs to do is keep putting out great Mario and Zelda based games and it will sell. That market is big enough to keep the Wii afloat.
