In an interview, Shigeru Miyamoto has confirmed a new Super Mario Bros. game for the Wii U will be shown off at E3 2012. Considering we already saw New Super Mario Bros. Mii as a tech demo last year, I think the game will be an expansion of that but it’s not completely clear. There’s always that (slight) chance they took it in a different direction. But we’re only a month and a half from the big event, so it’s not long now.
There’s also a quick mention of Pikmin, but Miyamoto simply confirms he’s still working on it, while also saying he has a other “small but important projects for Wii U” in the works.
You can check after the break for the footage I captured of New Super Mario Bros. Mii at E3 2011.
Update: The assumption I made was right, it seems. This is what Nintendo said:
…a new Super Mario Bros. game for the Wii U system will be shown at this year’s E3 Expo. This is based on the Mario experience that was demonstrated at last year’s E3 Expo.
But I’m sure there’ll be plenty of surprises, too.
