there was a guy selling a 3 hour plus cut of the film on ebay with pre viz and a temp track, but he was pulled from ebay. Don't know if this is the same as workprint because i have not seen it, but i have read the screenplay and novelization and i know there was a lot of deleted scenes even stuff that won't end up on the dvd. Also John Williams wrote more music for the movie than ended up in the film. Too bad theres no ultimate score for episode II or III like episode I. Just like the original star wars lucas was revising the script as the movie was being filmed, so we won't see rough cuts on the dvd. Too bad he won't release the star wars holy grail, the rough cut for episode IV, which only exists in a silent black and white film on 3 reels with partial dialogue and sound that drops out. The Color dailies footage still exist though so this cut could be restored.
