A new 3D Mario action game from the Super Mario Galaxy team and a new Mario Kart title are in development for Wii U, and will be revealed at E3, Nintendo president Satoru Iwata revealed during a Nintendo Direct presentation this morning.
Details about the titles are slim, but Iwata promised that the games would be in a playable state at this year's E3 conference in Los Angeles, Calif. this June.
This year's E3 will also see the reveal of the first screens for the next Super Smash Bros. game for Nintendo 3DS and Wii U.
A new party game is also in development for Wii U from the creators of Wii Party, which will launch this summer. The title features mini-games strewn across a board game environment (similar to the Mario Party series). Each mini-game title will either use a combination of Wii Remotes and the GamePad, or the GamePad by itself to have players square off against one another, as seen in the Twister-like mini-game above.
