2K Games tease Bioshock announcement

Take Two Interactive did not want to let the Bioshock franchise die with the closure of original creators Irrational Games, and handed the franchise over to 2K Marin (Bioshock 2). Today on the official 2K Games twitter the image below was posted with the comment - "Oooo, what COULD this mean?!"

Pictured is an advertisement for Eve's Garden - a stripclub found in the original Bioshock's Rapture. What could this be about? An HD remake of the original? The almost mythical PS Vita title? A mobile game? Or perhaps even Bioshock 3? With Comic-Con happening this week and Gamescom in just a few weeks we're likely to know more soon.
