Break out the flying pigs, as Gearbox tweets they are indeed working on Duke Nukem Forever as rumored. They say: "ALL HAIL THE KING!! Duke is back! Come check us out at the 2K booth at PAX!" Piki at Pax (thanks Rhialto) has photos of some of the Duke materials on display at PAX, and here's a twitpic of Gearbox's Randy Pitchford in a Duke shirt. No doubt there's more to come on this, in the meantime, always bet on Duke. Ustream.TV has live coverage from PAX which is sort of working, and they say fans at the show are getting to play the game firsthand.
