We have heard nothing for a long time but this was posted on Apogees own forum:
Still not much news on Duke Nukem Forever, in fact there have been 9 titles released since that was announced in 1997.

QUOTE said:Both the DS and PSP versions of the game are coming along nicely. On the DS side the graphics are blowing the socks off everyone who sees it (those lucky few outside the company that have seen it), and on the PSP, they say the depth of view is the best they have seen to date for that device. Development is proceeding at a feverish pace on both systems. There has been implementation of some unique features specific to each system that owners will be glad to see. We are also including some cool bonus game play features that we haven’t spoken about that we feel will enhance the overall way the game is played. That’s all we can say for now, other than stay tuned, more info in greater detail is on the way!
