BioShock sequel for 2K Boston and 2K Australia

News: 

Now, we know Irrational Games Australia / 2K Australia had a little hand in developing BioShock, and it looks like they can look forward to working on it some more! From the same Take Two conference call that revealed the delay for Team Bondi's L.A Noire, comes news that BioShock will receive a follow up. BioShock sales have been so good that a sequel was warranted, with Take-Two chairman Strauss Zelnick touting some impressive numbers during the conference call. From Shacknews...

Another analyst asked Zelnick about the sell-through numbers for BioShock, since the company has revealed shipment numbers of 1.5 million, but not retail sales. Zelnick would only say Take-Two thinks BioShock is "one of the fastest selling games in video game history."
