Well, just got past taking a good hard look at all three BDs myself, and while I don't own a surround sound system (yet), I can definitely vouch for the picture quality. It is unlike anything Star-Wars related I have ever seen before.
If my Star Wars Complete Saga box arrives, I can damn well guarantee you I will take this set over HD pink sabers any day.
Even coming straight from my television, rather than a sound system, the audio is still noticeably better than any other DVD release, and comes pretty damn close to ordinary run-of-the-mill BD audio master tracks.
I'm not going to go in extreme detail, since so many have done this before me. I can only say I totally approve their reviews, and embrace this set wholeheartedly.
These are keepers. Fine job DJ, damn fine job.
