Crush 3D is coming out in March in North America, according to representatives from Sega. It was most recently scheduled for release today.
Previously, Crush 3D, a port of a 2007 PSP game, was slated for a September 2011 release, but was delayed because Sega wanted to hold the game until the 3DS sold more units. A February 2012 date was announced back in October, but the title was moved up to January 10, 2012 in December.
This isn't the first time Sega has revealed a last-minute delay. In late 2009, Xbox 360/PlayStation 3 title Alpha Protocol was delayed to June 2010 on the day it was supposed to come out.
UPDATE: Crush 3D is still scheduled to come out in Europe on January 13 according to Sega representatives.
