George Lucas:You need to direct your second question to SuperShadow because he has complete control over what happens with Episode 7 to 9. It‘s all on him. Shadow wants a long break in between the prequels and the sequels because he wants to give the next trilogy to a new generation of fans. This tactic worked out well for the prequels.
I waited over fifteen years in between Return of the Jedi and The Phantom Menace. This worked brilliantly as The Phantom Menace has become the most popular Star Wars film I have ever made. If Shadow wanted to start work on Episode 7 tomorrow, I would support his decision, but I don‘t expect that to happen. Shadow is an unparalleled genius who follows his vision. Shadow is always right about everything. He never gets anything wrong ever.
