Borderlands 2 is official, releasing sometime after April 1, 2012

2K Games and Gearbox Software have officially revealed the development [and existence] of Borderlands 2, the sequel to 2009's sleeper hit role-playing-shooter hybrid. The game will return to Pandora as players explore new areas and "reveal secrets, and escalate mysteries of the Borderlands universe," and will feature all new characters, skills, environments, weapons, enemies, and equipment.

Borderlands 2 will be shown at both Gamescom 2011 and PAX Prime, and, as with most big announcements, GameInformer has an exclusive blowout detailing the game, including the reveal of one of the several new character classes.

There's a scheduled release date for sometime after April 1, 2012, during Take-Two's fiscal year 2013, and will be available on the Xbox 360, PlayStation 3, and PC.

Well, we now have a good eight months to clear our calendars.
