Originally rescheduled for a release on February 10, 2008, online retailers GameCrazy and GameFly are now listing Nintendo's anticipated Wii fighter Super Smash Bros. Brawl for a March 2008 release. Additionally, a trusted source has told NintendoWorldReport that Wal-Mart has updated its corporate database to reflect the change.
It's worth pointing out that Nintendo's press site still lists the February 10 date. However, retailers usually receive word on release date changes before us.
