The long-awaited Vita port of Borderlands 2 is coming next month. On May 6, Sony will release a hardware bundle which includes a Vita Slim, 8GB Memory Card, and the game for $200. The game will then be available as a standalone purchase on the PlayStation Store and at retail one week later: May 13.
The Vita version of Borderlands 2 will support cross-save with the PS3 version, allowing you to continue your adventure on either platform. In addition, the handheld port will include six add-on packs: Captain Scarlett and Her Pirate's Booty, Mr. Torgue's Campaign of Carnage, the Psycho and Mechromancer Character Classes, as well as the Ultimate Vault Hunter's Upgrade Pack, and the Collector's Edition pack.
