Actually your opinion is sort of right. The Wii is bringing in more gamers and as they get hungry for more games the HD consoles (PS3/X360) will be there to provide them with that experience.
Games like Gears of War, Halo 3, and etc.
Currently Playing: The Legend of Zelda: Twilight Princess (Wii), Halo 3 (X360), Brain Age (NDS), Pokemon Diamond (NDS), Warhawk (PS3)
