I gotta hand it to you Harmy, i rented the OT blu-ray discs from Blockbuster (not buying them due to the usual bullshit additions/changes), just to compare the PQ to your discs. All i have to say is i will never feel the need to buy these shit releases now that i have the despecialized versions in 720p. Fine, fine work sir!
At first it bummed me out, the blu-ray set being the very first set of star wars on home video that i'm actually NOT purchasing. I bought nearly every official release of the OT, the CED's, VHS's (3 times), Laser Disc (twice), and the DVD's (twice) (not to mention literally countless collectibles, t-shirts, action figures, posters, video games, books, comics, board games, etc. i've made my contribution to Lucas's $3billion+ net worth). As amazing as your set looks compared to the blu-ray discs, i won't be losing any sleep over it now. Thanks again!
Of course, the sucker that i am, IF the UOT ever does get released on blu-ray or any future HD/Ultra-HD format, i'll surely buy them. I just doubt it'll ever happen in my lifetime, as Lucas is handing his empire to his indoctrinated daughter.
