Nintendo unveiled a new Super Mario Galaxy 2 trailer and officially announces a release date for the highly anticipated sequel.

Super Mario Galaxy 2 was unveiled at last year's E3 to everybody's excitement. Now Nintendo has released a new trailer for the game and also announced when we can get our hands on it. The new Super Mario Galaxy 2 trailer was unveiled at the recent Nintendo Media Summit 2010. It shows off more gameplay footage including the new drill that looks really cool. It allows you to drill through a planet and come out the other side. That adds a lot of gameplay variations to the game and it looks like Nintendo is taking full advantage of it. SMG2's level variation and creativity looks awesome and the bosses look pretty cool too. We also get to see the new and improved Yoshi in the new trailer. He is now able to use his tongue to swing and pull with and he gains different powers whenever he eats the fruit lying around. One such power that is in the trailer allows Yoshi to inflate and then float up like a balloon. It's a pretty cool trailer that definitely should get Mario fans really excited.

Super Mario Galaxy 2 is going to be released exclusively for the Nintendo Wii on May 23rd. Check out the new gameplay footage after the jump.
