During a confernece call with shareholders today, Take Two head honcho Strauss Zelnick said that the Bioshock movie may launch in conjunction with Bioshock 3.
Hmmm... so a trilogy at least. Interesting.
Zelnick also implied (obliquely, to be sure) that Take Two has little creative control over the film. Because Universal will take all the financial risk, it stands to reason that they have all the control.
