Super Paper Mario, Mario Galaxy, Smash Bros Brawl, the new Zelda coming out, Prime 3, Duck Hunt 2.
That's just off the top of my head.
That's Wii itself, Virtual Console classics confirmed for 2007:
Super Metroid
Mario RPG:Legend Of The Seven Stars
Vectorman 1
Duckhunt
Metroid 1
Pilotwings
Street Fighter 2 Turbo
I'd say the Wii is easily considered possibly the best console of this generation. I think it's safe to say Nintendo and Microsoft are crushing Sony this generation, six exclusives made by Sony Computer Entertainment of America aren't enough for Playstation 3 to take over.
Final Fantasy 13 can easily be ported to 360, as well as MGS4 in due time. I'd say in the fall Sony may sell 2-3 million more in preparation for Ratchet & Clank, MGS4, FF13, and the few other exclusives made by SCEA.
