Don't act like Wii owners wouldn't want Banjo. That's like a 360 owner saying "Well who gives a damn about Metal Gear it's more movie than game anyway."
If Banjo as is (lesser graphics quality and slight changes of course) were announced for the Wii. Pretty much everyone would be excited about it and any attempt to say otherwise would be a blatant lie!
Anasui who said this would be a Mario Galaxy killer? Also while we are on the subject I wouldn't be remotely surprised if this game did in fact end up being better than Mario Galaxy.
They're already off to a great start and if they nail a lot of the things in this game and challenge gamers to become creative with the types of things we need to complete objectives along with some consistently strong level design throughout, I can see Banjo : Nuts & Bolts being the top platformer for some time to come.
It probably wont review as well as Mario Galaxy did, but the potential for it to be better is definitely there based on what we know so far.
