While I respect Lucas very much as a Creator, I dig the prequels, and support his right to modify his films any way he sees fit -
the fact that the Library of Congress has yet to receive a copy of Star Wars , and probably never will, is unfortunate and unsettling. It suggests his constant edits have destroyed the original film. (Star Wars trilogy was edited for every video release, to some extent, and only the original film that received the Oscar is admissible)
I have started viewing Harmy's DESPECIALIZED editions, and I have to say, if you're an old Grog like me you will appreciate these. What an amazing effort. It's not "easy" to acquire them, but nor is it hard. Anyone who ever wielded a C64 will find it a walk in the park. It is well worth the effort. 720p, color-corrected to the original palettes, and painstakingly restored to as close to original condition as you're going to find, at present. You'd be amazed how many little changes were made even before the SE.
This doesn't mean I hate the SE's - I don't - I have purchased the trilogy many times, and enjoy the process and journey of it all.
If you see news of an original print of the films reaching the LoC, you can expect an official Blu-Ray release. Until then, I believe all speculation will be fruitless.
