The ball is in Lucas court all he has to do is restore the original trilogy from 77-83 and make it viable for future generations of film fans.
Not just for DVD and Blu Ray, the existence of the movies on restored film prints need to be worked on for archival versions.
Fans like me could not care less about the special edition and prequels if we could watch the movies in a modern transfer that is not twenty years old, from thirty year old analog video format.
