Alan Wake's American Nightmare may be coming to a PC near you in the future.  DSOGaming found an entry in the Steam registry for the game, indicating that it could see a release at some point in the near future.

This would be a big plus for PC fans, who responded well to the original Alan Wake when it was released on PC.  Alan Wake's American Nightmare tells the story of the eponoymous Alan Wake. The unlucky writer continues his story, fighting against a malevloent force which has now taken on a personality and appeareance that mirrors his own, fighting to save reality from its evil.

Alan Wake's American Nightmare is currently an XBLA exclusive title.
