NSMBWii vs GT5 (AKA I just made a bet, tell me if I'm an idiot)

My bet is with Gran Turismo 5.

I cannot see New Super Mario Bros. DS type legs for NSMBWii. The game has more portable appeal. Like Monster Hunter.

My prediction is 3 million for NSMBWii, unless Nintendo bundles something with it.

Can we make a bet out of that?
