A tweet from 2K UK teases something related to BioShock Infinite, showing an image of Booker and Elizabeth. This may be something new or a collection of previously released material, a theory that's supported by the trophies displayed in the background. Sounds like we'll know soon enough, as word is: "Good morning from Booker and Elizabeth! Hope you all have a fantastic day! It's going to be an exciting one!" Thanks nin.
