Is 3D Mario doomed?

3D games are the standard, and Mario will always be represented in that format. Not only that, but Mario's flagship games will always be in 3D. This is Mario's first real 2D game on a console since what, the SNES? No, 3D is going nowhere.

And hey, am I the only one who thinks Galaxy 2 will beat the 2D game? To be blunt, I'm waaaaaay more excited about Galaxy. I had fun with the DS Mario game, but something about it on the Wii ... I dunno. Something tells me it won't do numbers anywhere near what the DS game did. And I'm thinking more people want Galaxy. Both games will be hits, no matter what.

No way Galaxy 2 is gonna sell better than NSMBWii - no way.  SMG2 is not gonna perform better because you're more interested in it.  And we already know that NSMBWii won't sell as well as NSMB on DS - that much is obvious.

How do we already know that NSMB Wii won't outsell the DS version?  I don't recall anyone thinking that Mario Kart Wii would outsell the DS version, but it did.
