Take-Two expects Infinite to become the 'highest-selling release' in the BioShock franchise.
Second DLC, Burial at Sea, is a two part add-on campaign featuring a new story for Booker and Elizabeth.
Expected to be DLC for BioShock: Infinite, definitely isn't info on a PS Vita game.
BioShock Infinite also in the deal, but its cut down price of £34.99 begs to differ.
Has been in development since the game shipped, but it takes time.
