See, here's where I disagree. The Wii's first year success was basically owed to two games: Wii Sports and Twilight Princess. The reason being that those two games (much like Brawl and Wii Fit) combined cover a much wider demographic than two games like Halo and Bioshock - which are targeted at the same audience. Not that those were the only two games that people bought, but that combination made the system a must buy for both core gamers and the casual folk.I don't think Brawl and WiiFit are enough to carry the console through the whole year, much like Halo 3 and Bioshock isn't enough to carry the 360 through the whole year. The more quality games the better, it doesn't matter if Brawl and WiiFit sell 19 million copies, if they're 2 of the few games worth getting the hype with die quickly after release.
When I say that Brawl and Wii Fit are going to carry the system through 2008 (at least until the next holiday season) I mean that core gamers will buy the system for Brawl while casuals will continue their demand for Wii thanks to Wii Fit. Having two system sellers that appeal to two distinct audiences will absolutely inflate hardware sales until the Wii is the ahead in Norther America and cements its lead worldwide.
