Wii already won in Japan, and at this rate it will surpass 360 this summer.
Although ido think Halo 3 will make 360 surpass Wii again, Wii may overtake again int he long run.
It seems to me Wii to this gen what Gameboy was to the SNES/Genesis.
It's weaker then the rest but DAMN it sells good.
I LOVE MY WII!
