"Duke Nukem Forever developer 3D Realms is shutting down, according to Shacknews. They cite 'a reliable source close to the company,' who said the developer is finished and employees have already been let go.
It looks like all of the Duke Nukem Forever jokes are turning into reality; DNF might turn out to be the ultimate vaporware after all."
3D Realms' webmaster, Joe Siegler, confirmed the closing, saying that he didn't know about it even a day beforehand. Apogee and Deep Silver, who are working on a different set of Duke Nukem games (referred to as the Duke Nukem Trilogy) say they are not affected by the problems at 3D Realms.

And a recap.

Take-Two Interactive has now sued 3D Realms over the cancellation of Duke Nukem Forever . Take-Two did not provide continuous funding for the game, but they did pay $12 million for the publishing rights to the game. A Bloomberg report quotes Take-Two's complaint as saying that 3D Realms "continually delayed the completion date" and "repeatedly assured Take-Two and the video-gaming community that it was diligently working toward competing development of the PC Version" of the game. (The complaint refers to 3D Realms as part of Apogee Software, Ltd., not to be confused with Apogee Software, LLC, the publisher behind the still-forthcoming Duke Nukem Trilogy.)

Maybe Take-Two can be rewarded the IP and all progress related to the game. Altho I don't know if any other companies have invested in this game as that would complicate things.
