Microsoft across pretty much all their product lines like to create (market leader + refinements) type products until they become the market leader. They created a better ps2 with the xbox 360, and now that the market leader is the wii I think they are going to create a better wii.
1. Xbox Freestyle
2. Christmas 2010
3. New motion controlers, a snes->psx type of upgrade from the wii's motion controllers
4. Very good shot
5. Zune line will become their handheld
