This fact was revealed by Epic Games producer Rod Fergusson to gaming TV show X-Play via their twitter account.

Aside from the release month, no other detail has been shared. Of course, it’s also worth noting that March 2013 will also see the release of Square’s Tomb Raider reboot, THQ’s South Park RPG and another GoW — Sony’s God of War: Ascenson — will also be out within the month.
Needless to say, better save up now as March is going to be one heck of an expensive month!
