Do you really think that George bothers himself much with games Lucasarts has in mind? If I was a billionaire I know i wouldn't..
Anyway, the past years I was rather confident that a Kotor III will be available eventually. But I don't believe in it anymore. Perhaps it is time to accept that there probably won't be a next Kotor.
IF there's a next one I'd wish Bioware developed it. But the chances of that happening appear to be next to zero. Well, Obsidian, given they get enough time, should do an equally good job.
