You are guarenteed to get one from walmart.com if you get the bundle. You just have to be able to bite the big purchase until you get the games, then you can return them and recoup your money. It really is a surefire way to get one, I don't know why more people aren't doing it.
Although, you aren't missing too much right now, the best games are multiplayer and they are just minigames. Zelda and Excite Truck are about the only good single player games out there right now (IMO).
But next month Super Paper Mario comes out and that should be awesome.
