Nintendo has kicked off its E3 2009 press conference and many are anxiously waiting to hear what Nintendo has in store for gamers at the show. Right out of the gate Nintendo's Cammie Dunaway announced that there would be a new Mario game for fans to enjoy.

Dunaway announced that a game called New Super Mario Bros. for Wii is coming and supports multiple players for up to four people in a side-scrolling game that pays homage to the original very well. The game offers main mode and a co-op mode and players can switch at any time between the two.

Mario sports a propeller cap to fly upwards in parts of the game reports Joystiq which is activated by shaking the Wii remote. At the end of the multiplayer game players are ranked based on how many coins they collect.

After Mario, Dunaway moves right into a new Wii Fit game called simply enough Wii Fit Plus. The new Plus version helps users find a specific exercise regime just for them. The game offers six strength and yoga training activities that are new and allows the setup of playlists for exercises. Wii Fit Plus also keeps track of the amount of calories players burn during their workout. Wii Fit Plus will be out this fall.

Nintendo's Reggie Fils-Amie talked about the Wii Motion Plus accessory that has been talked up for a while now. The demo of Motion Plus also included some Wii Sports Resort play reports Joystiq. Everyone starts the game by parachuting out of an airplane. Archery was demoed along with other aspects of the game. Wii Sports Resort launches July 26.

Tiger Woods PGA Tour 10 was next on the agenda with talk about the bundle that comes with the game. EA Sports will offer the game with the Motion Plus accessory and without. Red Steel 2 is the follow up to the popular sword play game and will require the use of the Motion Plus accessory.

Another new Mario game is coming to the Wii called Mario & Luigi: Bowser's Inside Story. The game is a side scroller with RPG aspects set inside a massive dino-monster's digestive system. Sounds weird. The game is set to launch this Fall. Another Mario game called Mario vs. Donkey Kong: Minis March Again is coming to DSIWare June 8 and is much the same as Mario vs. Donkey Kong with the addition of a full level editors and the ability to share custom levels online.

Dunaway came back on stage and has announced a second Mario title for the Wii, a sequel to Super Mario Galaxy called simply enough Super Mario Galaxy 2. The game has Yoshi and Mario on some worlds reports Joystiq. Yoshi can get power-ups that allow him to blow up like a balloon and a large button freezes water allowing Mario to run on the frozen lake. Some of the games levels are 2D side scrolling action.

One of the biggest announcements at the conference was a new Metroid game from Nintendo and Team Ninja. The game is set for a 2010 launch and is called Metroid: Other M, the game apparently has some of the back-story to Samus Aran.
