Nintendo held their Media Summit event in San Francisco yesterday providing a sneak peak inside the coming year for all things Nintendo. Among the topics were Metroid: Other M, Prince of Persia: The Forgotten Sands, the DSi XL, and the always popular Super Mario Galaxy.  Last year during the E3 conference, Nintendo unveiled the trailer for the Mario Galaxy sequel along with a TBA 2010 release date. As of the Media Summit, Nintendo has announced that Super Mario Galaxy 2 will ship May 23rd.  Expect the same amazing gameplay we saw in Mario's first trip into outer space as Yoshi and friends tag along to presumably save the princess from yet another abduction.  If there's ever a game — or two in this case — that justify the purchase of a new console, this would be it.  If you own a Wii, budget an extra $50 for May.
