"OMG, Duke Nukem is at PAX!" At least, according to an effusive tweet from Joystiq alum Dustin Burg. In addition, a source at the convention told Joystiq that images of Duke Nukem are visible at the 2K booth, which has yet to open to the public. The Gearbox logo can be seen, but the title of whatever Duke Nukem game is being promoted is currently covered.

However, we might have a clue, thanks to reports coming in from CVG's "US dev sources," who tell the site that the game is actually Duke Nukem Forever, and will be given a "grand demo" at the show. Rumors have been flying recently about Gearbox signing on to complete the game. Also flying: pigs, in an image tweeted by 3D Realms' George Broussard. 2K did say it planned "something big" at its booth, and this would certainly qualify.
