Each time I do a trilogy it's ten years out of my life. I'll finish Episode III and I'll be 60. And the next 20 years after that I want to spend doing something other than Star Wars. If at 80 I'm still lively and having a good time and think I can work for another 10 years between 80 and 90, I might consider it. But don't count on it. There's nothing written, and it's not like I'm completing something. I'd have to start from scratch. The idea of a third trilogy was more of a media thing than it was me.
