At the Nintendo E3 2009 press conference, the company introduced the Wii MotionPlus, an attachment which delivers precise and distinct motion control and a new Super Mario Bros game.

The Wii will be released later this year including the new “Motion Plus” which Reggie Fils-Aime, President of Nintendo America said will make the users gaming experience more realistic.

For example, when gamers utilize the tool in a game of golf or a sword fight, the sword or golf club will move in the exact manner in which you’ve moved it off screen bringing for a more realistic feeling while playing the game. Only games that are coded for the new device will be able to support it.

The company also announced a brand-new Mario title, New Super Mario Bros. for the Niintendo Wii.

The 2D side-scrolling game will feature four-player co-op along with new game play features and power-ups. The game automatically zooms and pans so that all four players are always on screen.

The new Super Mario Bros. will be released this holiday season.
