From Joystiq:
I went to Vegas and I bet it all on Duke and all I got was this lousy--It's finally, really, actually ... maybe going to happen at this point. The rumors are true: Gearbox Software and 2K Games have taken on the Herculean task of completing and releasing 3D Realms' unfinished Duke Nukem Forever. The project was officially unveiled today at PAX during a livestreamed presentation at the 2K Games booth and announced for Xbox 360, PS3 and PC. "It's coming out in 2011," Gearbox president Randy Pitchford said during the presentation. (Of course, we're skeptical about any release date associated with this particular title.)
Gearbox began finishing Duke Nukem Forever in late 2009, according to The Wall Street Journal. "Clearly the game hadn't been finished at 3D Realms but a lot of content had been created," Pitchford told WSJ.
"We're in the polishing phase now. This is a game where we can not make a promise we can not fulfill," Pitchford added. "We need to get past the shock and awe, and then we can go to all the retailers and first parties and work out a launch plan."
