UPDATE: Nintendo Announces Two New Mario Games for the Wii

Nintendo has announced both a new Wii version of the popular DS game New Super Mario Bros. and a sequel to Super Mario Galaxy.

The first title, New Super Mario Bros. Wii will bring four-player cooperative gameplay to the Mario universe. We'll be taking a look at a playable version later this week, but for now, it looks a lot like LittleBigPlanet without the weird depth-hopping. The game is set for release this holiday season.

Meanwhile, Super Mario Galaxy 2 picks up where the previous installment left off with a new addition to the cast: Yoshi. It's nothing more than a gameplay trailer at this point, but if it's half as fun as the first Galaxy, it's something to look forward to. No word on a release date yet, so don't expect it to come out this year.
