Duke Nukem Forever was on preorder in 2001, too. The status of DNF is "never" until people are actually playing the game...just because it's on preorder again doesn't mean it's actually going to come out.
The obvious connection, of course, is that the developers of Duke Nukem Forever needed to read Volume 4A (in fascicle form, at least) in order to actually complete the development of the game. ;-)
Which means you can catch Atlas Shrugged [http://www.imdb.com/title/tt0480239/] in a movie theater near you before you play the game.
