Take Two has presented their latest financial results (poor ones, but better than last year) and among the information was some sales numbers on the Bioshock franchise. Bioshock 2 has shipped in three million copies worldwide, and the original just saw its sales reach 4 million as Take Two noted an increase in sales of the original with the launch of the sequel. Ubisoft noted the same thing when Assassin's Creed II launched last year.
