Mario is coming to 3DS in full force, with Mario Kart and Paper Mario already announced for release within the next year, but of course Nintendo is bringing 2D and 3D Mario platformers to 3DS. Nintendo President Satoru Iwata has recently tossed out a tiny scrap of information, and although it's not much to go on it's still Mario on 3DS.
According to an Andriasang translation, Shigeru Miyamoto's EAD group has Mario running into the screen and striking blocks that float in the air. Of course, this could describe pretty much any 3D Mario game since Super Mario 64, but Iwata promises good things ahead:
We're making software that is packed with the kinds of surprises and enjoyment that the 3DS can deliver.
Hopefully we'll see Mario's platforming outings at this year's E3 in June.
