The amazing thing about these Despecialised Editions is not that they are perfect...they're not, and never will be. What's amazing about them is the incredible amount of care and research that has gone into every "frame"...especially the colour correction.
Let's say Disney/Lucasfilm ever did give us the an HD version of the OT...is there anyone who thinks that they'd put as much care and meticulous research into how the film looked in 1977 as is evident in this set? Does anyone think they'd consider carefully how every moment of the movie looked? Would they attempt to match the subtitles of the original release? The colours? Would the reproduce the 1977 audio mixes? Of course they wouldn't. When, and if we ever get the OT in HD, I'm sure it will have plenty of beautiful 1080p or HD detail...maybe even a 4K scan. But I have absolutely no doubt they'd f*ck up the colours at a minimum. It will be a slick presentation made for contemporary tastes and sensibilities. But it won't be any kind of preservation.
So no matter what, these DEd's are going to be a part of my HT collection for a long, long time.
