The Adrenaline Vault News has posted an interview with 3D Realms' George Broussard, following up on the recent announcement that there would be no E3 showing of Duke Nukem Forever. Here's a quote talking, and not talking, about the state of technology in DNF:

Broussard also said the technology is 90 percent complete. “The remaining technology falls into two classes. Technical things to fix in the way the engine operates and implementing new technologies. We recently completed our bones-based animation system, and it's in the game using our motion captured data. We do have one more piece of significant technology we have created to implement in the game, and no, I'm not discussing it,” Broussard finished with a grin.
