Where is it?! I love playing the Nintendo DS version, but I need New Super Mario Bros for Wii. Nintendo, please port the game to Wii! Either Nintendo will release an official New Super Mario Bros for Wii or the emulation scene will develop a DS emulator for the Wii that'll allow everyone to play our favorite game EVER!

If you haven't seen what the New Super Mario Bros for DS looks like, check out these commercials from around the world:
