Well, it's about time. Back when the original Special Editions were releasing in Theaters, he was saying that he originally had 9 stories planned out. When the prequels came out, suddenly he was swearing up and down that he only had 6 stories planned out. Interesting to see him possibly retracting that.
Man, though, we'll never hear the end of the whining from the Expanded Universe people if the last trilogy becomes a reality, judging by their (if I remember correctly) reaction to the prequels.
