It should be enough to suck the wind out of many a preservationist's sails. Keep in mind that the '04 set, despite ridiculous color, audio and content changes, still sold tremendously well. Hell, the O-OT is being sold as an "added bonus". You could look at it as Lucas making sure his loudest detractors are forced to buy his bastardized editions in addition to their favorite version.
I knew he'd never have the balls to sell them seperately.
