The 93 piece of crap master is still used for the unaltered trilogy. The 04 even more piece of crap master will be used for at least the same amount of time and be re-released as often. At Lucasfilm you create a video master for the long haul, so laden with glitches and errors that people will be forced to upgrade for years.
Great. (hit with Ewok stuffed plush toy) "Just what I've always wanted."
No one making Blu-rays, save for Criterion, Kino and the Eureka Masters of Cinema series in the UK, actually cares about the films they are representing. It is merely a source of revenue. The only cases where mistakes have been acknowledged are where mass amounts of people complain to the studio and enough bad press is generated about the disc so that revenue is threatened. Otherwise, the studio will not strike a new transfer. (Gladiator, Predator, Gangs of New York etc.) Spartacus is an extremely crappy port of the HD master that has been further screwed with. Even Robert Harris can't believe some of the crap they did to it. The Criterion DVD and LD blow it away as far as color and detail are concerned. And don't even get me started on how badly William Friedkin destroyed The French Connection. It's so bad that the cinematographer disowned the film entirely.
Did any of the people who worked on these new Blus ever see Star Wars theatrically? Do they even know what dye transfer means? Or anything about all the various different sound mixes, edits, versions, cuts, tweaks or fixes? Nope. Does George? No not really.
