It's sad to think that KotOR II will never get the follow up it deserves. There was alot going on for a sequel and if we can gather anything from TSL about what a possible third game would have been like it is:
-Involves Revan's ability to convert Jedi/Soldiers to betray there own people etc, Ancient Sith teachings?
-Restoration of the Jedi/Republic/Mandalorians/Devastated Planets
-Exploration of Unknown Regions/Revan plot payoff.
Probably missing a few, and of course follow up to all the pivotal characters, hopefully K2 party members included. Obsidian should contact Disney and pitch a new game.
