"Why fight them when you can do it yourself.
Why do you want the preservation of this movie to come from George Lucas?"
Because Lucasfilm has the money, employees, equipment, and most importantly, the original negatives and film elements, all of which means that Lucas has the capability of providing us a fantastic quality release of the OT. He has chosen once again not to do that. Take a look at the Blu-ray release of Blade Runner - all 4 versions of the film, all remastered, with the film scanned at 4k resolution, and the effects shots scanned at 8k resolution off a pristine 65mm negative. Do you honestly think any Blade Runner fan could do that? Look at the Blu-ray release of Wizard of Oz - simply stunning. I thought "It's a Wonderful Life" looked remarkable. Look at the work that went into the incredible blu-ray Alien set.
Do you honestly think that fans could produce that kind of quality? I don't mean that in any way to sound negative to all the incredible fan editors out there - on the contrary, I have seen some truly amazing work done by fan editors. And some really amazing extras packages put together also (Editdroid comes to mind). And some really original stuff too, like the amazing "Story of Star Wars" by MoveAlong.
But lets be honest here. Lucasfilm has access to high-end equipment and most importantly the original film prints. There is only so much fans can do with what is available to them for sources. Lucasfilm has the ability to release a set just as good as others I mentioned above. That is all we are asking for, and I don't think it's too much to ask. Neither do most of us here. Obviously Lucas feels differently.
