Huh, I just realized that SSBB has sold a lot less than I though, Galaxy type numbers. Maybe I'll end up being right and that Mario Kart Wii will be the best selling (non-bundled) game on the Wii? That would be fun!
OT: Zelda should be able to move 6 million lifetime easily and I'm fairly certain it'll pass 7 million as well. I'll say 750k first week (ww), a tad less than TP but it'll have higher sustained sales for longer, landing it higher lifetime sales over time. The word will spread, a few will be skeptical at first since they're making some changes but they'll come around and this title will stand out (as is always the case with Zelda games) as one of the better games of this generation.
