Book on Korriban
Now I'm not completely sure about this but my friend's dad's business partner knows this writer and she says that he has permission from Lucas and is going to write a book on Korriban. Now this may not be true but it sounds really good. It is set in between Fall of the Sith empire and Exar Kun's time. The plot is basically 3 archaeologists go on a voyage to Korriban in search of an artifact, and everything goes wrong and they come face to face with some of the most powerful ancient sith. She got the impression that the jedi (like Odun-Urr) would not make an appearence, but some completely unknown ancient sith will appear and some others that we already know a little about.
Now again, I am not completely sure if my info is correct, but it sounds pretty cool.
