I hope you at least address the prequels. I'm sure you'd do a fantastic job, and I'm content to let Adywan handle the OT. I always read your thread, as you truly are a miracle worker!
No pressure at all, since I imagine this project will take a couple of years at least, but out of curiosity, how long do you anticipate Ep. III will take? Do you think you'll have the energy to edit all three, considering how much time and love you're putting into this one?
