George Lucas won't shut up about this digital projection stuff. I can personally attest after seeing Episode II in a digital theater that the image quality is THAT much better. Even Roger Ebert, who has stubbornly refused to recommend the digital projection conversion, recommends seeing films shot digitally in a digital theater. TheForce.net has posted an impressive (if incomplete) list of theaters showing Star Wars Episode III: Revenge of the Sith in Digital Projection. So if you don't know, look, and if you do know and the theater isn't listed, help them out and submit.
