thekitchensink: I wasn't sure whether to include Trauma Center since the original game started out on the DS. Wii Series is a toss-up but they're all different games. I'll wait until they announce Wii Sports 2 or Wii Fit 2. Rayman is a spin-off so I decided not to include it. No confirmed sequels for Z&W or Disaster, Assassin's Creed, LBP, Scene It, EndWar.
Updated with Mass Effect and Lost Winds.
