There's an interesting article up over at Yahoo where the debate as to whether Mario can work his magic for the Wii, as he did on the DS. The fact is yes, while maybe not to the extent that New Super Mario Bros.
has done wonders for the DS, on the Wii the Mario brand is a guaranteed way to push units.
While Super Mario Galaxy
not being available at launch, or during the battle to come this Christmas when all 3 consoles are available on retail shelves, is sure to be a fairly-sized detriment to Nintendo, other first-party titles such as Metroid Prime 3 Corruption
and The Legend of Zelda: Twilight Princess
should help to carry that load.
Honestly, who doesn't like Mario?
