I'm a little skeptical to think that a new Zelda, SMG2 or Wii Vitality would help hardware sales very much. Just like a new Halo game on the X360 right now would barely move any hardware because everyone that wants to play Halo already owns a X360 (just look at Halo ODST and Wars). So that eliminates the new Zelda and Super Mario Galaxy 2. Now Wii Vitality, that's the tricky one it very well could end up like another Wii Music though. I'm sorry but I don't really see anything that exciting about knowing your pulse? Maybe it does other things as well but is it really a system seller, will people that don't own a Wii think hmm I want to buy a Wii to be able to use Wii Vitality, I don't really think so. I think it'll take the same fate as Zelda and SMG2, it'll sell a lot but won't move much hardware.
