Or they could just take the obvious and easiest solution (and one that makes the most sense given their trends and history with the Mario series)- New Super Mario Bros 3D. It'll be the third in the revival series they've got going on, and it fits their interest in putting part of the system name in the title of everything, plus cash in on the 3d pun. I'm going to bet on that. We've seen Mario 64, Mario Advance, Mario 64 DS, New Super Mario Bros Wii, etc. Plus, all the non-Mario "Super" titles on SNES. Makes sense that they'll continue the tradition. You kind of have to expect such an obvious move by now. I'll be shocked if they choose to ignore such an obvious naming opportunity.
