Nintendo of America's towering president stopped by the set of Late Night with Jimmy Fallon yesterday, closing off the show's week long celebration of upcoming video games with a look at Donkey Kong Country Returns. After teaching Fallon the correct method of Diddy-maneuvering, Reggie Fils-Aime brought out the big guns: The 3DS, which he told Fallon would be coming out "next year." Oh, that thing you just heard? That was the sound of one thousand Christmases being simultaneously ruined.
You can check out the Donkey Kong demo and Fallon's enthusiastic reaction to the handheld's glasses-less 3D effects in the video posted after the jump.
