Not only are they 'holding' a May 25th release date, there also appears to be a Smash Brothers 3DS box in the Gamestop picture as well, with a release-year of 2012. The work on Kid Icarus JUST finished, giving the studio very very little time to prepare the Smash title for this year. So remember it's all rumors still.
