Are we actually going to brag and argue about the shovelware shift from Wii to HD?
Wii already has more games and more backwards compatibility than any other console out right now, so a huge shift in the 5th year of a generation won't make much of a difference, especially if it's all party games. Everybody's already figured out what their favorite party games are over the past 4-5 years.
The other systems are only getting huge chunks of new games because they're launching Kinect and Move, with 10 Just Dance clones, 10 Wii Fit clones, and 10 Wii Sports clones each. For comparison, Wii Motion launched with one Wii Sports clone, two tennis games, and a golf game. The best game got to rise to the top, and it's sold over 15 million by now. If you launch a controller with tons and tons of games that are barely different from each other, you're not going to get a huge breakout success like that. Except maybe Dance Central... but it's still only 2 players instead of 4.
