I should mention that I don't expect them to change the Wii bundle until after Christmas when sales of the console and Super Mario Galaxy have slowed down. But still, if they didn't want to do Super Mario Galaxy or wanted to change the bundle before Christmas, Super Paper Mario would be another great choice as would Big Brain Academy: Wii Degree.
The reason a game like Big Brain Academy: Wii Degree would work (just like games like Wii Sports and wii Play works) is that it's a multiplayer game and makes people buy more accessories which is where consoles traditionally make their money (just like how movie theaters don't make anything off ticket sales and make all thier money from refreshments--ever wonder why they're so annoying about combo upgrades?).
