Just completed KOTOR2 for the first time today. Glad I'm not the only one who saw parallels with TESB, in that we have a rather unsatisfying ending with several loose threads waiting for a third instalment to bring things to a conclusion. (Or eight conclusions, depending on LS vs. DS in all three games - and variations on these as well.) I'm seriously hoping KOTOR3 does do this - 2 resembles the middle of a trilogy too much for it not to be one.
Or maybe I'm just being an optimist. We won't know for a while.
