If you're talking soley about games and not extra features to the systems, the Wii has them all beat. Its new design attracts many that were not once gamers, and still attracts those that were. Halo's large audience likely caused the high sales in 360's, or at least a vast majority. The PS3 didn't have much to brag about, really, which is why it did so poorly. I expect the Wii will be the most popular of this Gen of systems.
Of course the Wii is still going to be popular, but you're putting everything in the past tense when it's currently happening. Yeah, Sony needs to do something with its PS3 sales... Gran Turismo and MGS 4 are big exclusives, but those come out next year. Assassin's Creed is shaping up nicely, though. And, of course, Need for Speed Pro Street is going to the best on PS3's hardware. (It's multi-platform) Plus, GTA 4 is going to be one of the only games you'll even need, on 360 or PS3... I am definitely getting that special package it comes in - a metal safety deposit box, duffel bag, keychain, and a special cover, I believe...
