To the shock of no-one, Nintendo CEO Satoru Iwata teased the next main Mario title at the company’s 2011 GDC keynote. In case you weren’t already aware, it’s for 3DS.

“The announced 3D Super Mario game will feature traditional Mario game play and will fulfill the dream of Nintendo video game designer (and Mario creator) Shigeru Miyamoto to bring true depth and distance into the game’s mechanics,” said Nintendo in an announcement.

While details remain sparse, Iwata mentioned that the team behind Super Mario Galaxy is handling development duties. More information is promised for E3 2011.
