Nintendo launched their preview site for the New Super Mario Brothers game for the Nintendo DS, and it came with some bad news. According to the site, the official release date for the game is now May 21, 2006, a week’s delay from the last announced date. EBGames.com still has the game listed as coming in on May 15, 2006, but gamers can expect that to change. Nintendo softens the blow somewhat by offering some desktop wallpapers for download on the site.

Update: The official site release date has been changed back to May 15, 2006.
