@GTA: I thought it was implied after you go to Onderon, as I seem to remember somebody saying that the True Sith were going to use Onderon as a staging point, so I guess that caused me to think that the Sith invasion was about to happen. I've also thought that the True Sith were the ones who damaged the Ebon Hawk at the start of the game, but now I'm sure that's wrong.
