Anonymous "sources claiming to have knowledge of the situation" whisper to Kotaku that 3D Realms' eternally troubled Duke Nukem Forever is now in development at Borderlands developer Gearbox.  Naturally, it should all be taken with a big pinch of salt. 

Duke Nukem Forever as it was under 3D Realms in 2008. 

Duke Nukem Forever will be released under Gearbox's name, the sources claimed.  One indicated that a playable demo might be released later this year.  Unsurprisingly, DNF publisher 2K Games, creator 3D Realms and Gearbox have not confirmed this. 
While Gearbox involvement in DNF has been rumoured before, this time Gearbox president Randy Pitchford hinted that--in Kotaku's words--"he may be able to better clarify the situation further at this year's Penny Arcade Expo,"which runs September 3-5. 
However, Pitchford might be teasing news of the unannounced Duke Begins, which Gearbox had worked on but was described in mid-2009 as "halted" "for the time being." 
In May, 3D Realms and publisher 2K Games settled their legal battle over Duke Nukem Forever, potentially meaning Duke could return if only the game could be finished--which is unlikely to happen at 3D Realms after most of the studio was laid off. 
"We've never said that Duke Nukem Forever has ceased development," said 3D Realms CEO Scott Miller in December 2009, explaining that "yes, we released the internal team, but that doesn't correlate to the demise of the project."
