They are the special editions, and there was talk at one point that they were redone yet again with some of the f/x cleaned up and a 5.1 mix, but I have no idea if that is true. Lucas said that he has no intention of releasing the original cuts on DVD. Friggin lame, IMO. If Greedo shot first, then the movies ended there. No way in hell he missed from 3 feet away. Besides that and the uber-lame Jabba scenes in Empire Strikes Back, I enjoyed the special editions.
That said, I will be getting these. Special Edition is better than no edition, and I don't own a VCR or Laser Disc player.
