Is Wii fit classed as a bundled game?
otherwise i would guess Super Mario Galaxy or Mario Kart....or Pokemon D/P, would be more accurate, although i don't know how it will fare legs wise in comparison to other DS games i think it has a chance at 20Mil, wheras Mario Galaxy and Mario Kart depend more on how the Wii's userbase expands but 15Mil should be easily possibly for either (and both).
SSB i dunno, it think it should manage 10Mil but i'm not sure if it will sell as much as SMG/MK
