Takashi Tezuka has said he'd like to be able to "exceed New Super Mario Bros." as well as work on something other than Mario.
Of course, he's worked on non-Mario titles in the past, but never in a significant position. I think this is interesting, he's a pretty great developer and has been at Nintendo for a VERY long time, so I'd love to see his take on other Nintendo franchises. (or on new games entirely) I'm also glad they plan to exceed NSMB, they've sucked every little bit they possibly could out of those games. :p
We will continue to make 3D and 2D Mario games, but I want to make one that even exceeds New Super Mario Bros. I can't say anything concrete yet, but you may see it within a few years. I also kind of want to seriously work on something other than Mario.
