I don't believe future fans will necessarily buy into George's numbering scheme. I think the fame of the films will be such that the numbering scheme will be recognized as an artificial construct and, even if the real first movie is remembered as "A New Hope" (arrrrrgghghgh!!!!), it will be widely known that it was the first movie of the 6 Star Wars films.
(Of course, if the movie could only be properly remembered as "Star Wars," it would always be patently obvious which was the first Star Wars movie. Bah.)
So, until such time as the relics of our civilization are dug up by beings from the 28th century, or from another galaxy far, far away ... I remain confident that all but the most clueless will know that the movies were created 4, 5, 6, 1, 2, 3. If some retard wants to first watch a movie labelled "1" that they know was really 4th, that's their perrogative ... but they will have no one but themselves to blame for Star Wars seeming lame.
Fortunately, not all the "youth of tomorrow" will be retards.
