In an earnings statement issued today, Take-Two Interactive again stated that BioShock 2 is due out by October 31, 2009, but listed the platforms it'll hit by then as "TBA."
The first BioShock debuted on PC and Xbox 360 in 2007, and arrived on PS3 over a year later. However, the PS3 port was not started until after the other versions released.
The advertising campaign for the the sequel, in development at 2K Marin, is now underway. The game will be featured on more than 30 magazine covers next month.
