The rumours would appear to be true. Borderlands dev Gearbox IS working on Duke Nukem Forever - and the game is set to be unveiled at Seattle games event PAX today.
US dev sources have indicated to CVG that the game will get a "grand demo" at the show - and will be built upon what 3D Realms had already created, rather than a fresh project.

Duke Nukem Forever originally began its life as a sidescroller instead of a shooter back in 1996, and that canceled version has just been leaked.
Very cool, but i don't know how real this is... I'll check it out later to find out.

Duke Nukem Forever, the troubled FPS from Gearbox and 3D Realms, has been restored to more traditional 90s shooter thanks to a sweeping “remaster” mod
kinda of a misleading title.
Mod features:
Sprinting removed and faster player movement
Jump height increased
Swim speed is much faster
Player can now hold breath underwater for 45 seconds instead of 15
Weapon rebalance and screen shake when shooting removed
2/4 weapon limit completelly removed
Quicksaves (F5 by default)
Depth of Field removed and new post processing effects
Driving sections are now in first person perspective
yw.

Duke Nukem Forever, the infamous and controversial FPS from 3D Realms, apparently looked much better before launch, as modders discover various cut features
Wow, that advanced lighting makes a huge difference to the visuals. I get that Gearbox tried to slap everything together and release a finished product. But it seems like they cut out a lot of content that would have made the experience more enjoyable. That's a shame.
I really hope they announce it today! But, I doubt it :(
it needs to die already
let this cancer die already
Hope so I want a new DUKE game I don't care how long it's taken as long as its good
back in the 80's
