At the end of the trailer, the targeted "2010" release date flashes on the screen. If you look above it, however, Samus's ammo count shows 3/25. March 25th, 2010 is a Thursday, an uncommon date for game releases, and March is a bit early for a title this big. Then again, Nintendo often releases games on strange dates, and Metroid Prime 3 came out in August.
