According to gaming website GameFront.de, Star Wars: Knights of the Old Republic 2 (also known as KOTOR 2: The Sith Lords) will be released in Feb 2005. Here are more details (translated by RPGDot.com):
The game is set five years after the events in the original game. You are a Jedi outcast who returns to the Republic which is in a shattered state after the Revan Malak war. The Jedi Order is hiding in the Jedi temple ruins on Dantooine.
Revan and HK-47 are going to be part of the game again. Revan will not be a playable character. Ebon Hawk is going to return as well just as other characters from the previous game. Further details have yet to be revealed.
There will be no savegame import from the original game. The game engine is the same that was used for the prequel.
There is going to be a new Jedi "Prestige" class. The existing ones (Guardian, Soldier etc) will be there as well.
The subtitle of the game is supposed to be "The Sith Lords".
Anticipated release date: February 2005 (US version)
