A story on GamesIndustry describes 3D Realms' "foxing" of a Duke Nukem 3D modification for Half-Life 2, as the developer protects its intellectual property (thanks Gamers.com and Mike Martinez). The story goes on to casually state that Duke Nukem Forever, the overdue sequel to Duke 3D, will be making an appearance at E3, though it all sounds a bit speculative: "3D Realms itself is still working on Duke Nukem Forever, the long delayed sequel to Duke Nukem 3D, which is expected to be present at E3 this year in some form - although previous E3 showings a few years ago came to nothing when the project switched engine, and 3D Realms still refuses to commit to any release date for the title."
