Nintendo confirmed yesterday that it'll be showing off a new Mario game forWii U at E3, but those hoping for a 3D successor to the Galaxy series look set to be disappointed - unless the platform holder's keeping something big secret for now. We were hoping for Mario Universe or something along those lines, but Nintendo has said the Wii U Mario scheduled to be shown at June's event will be based on the tech demo from E3 2011.The "prototype" at last year's show featured four player gameplay set on 2D side-scrolling levels. Users could control Mushroom Kingdom characters or play with their Mii alongside Mario and the gang. You could also take the action away from the TV and play the game on the Wii U controller. A Nintendo spokesperson told Kotaku. "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." A new Pikmin game for Wii U is also set to be demoed at E3.
