I could be wrong but I have the below DVD version of the original trilogyhttp://www.amazon.com/Star-Wars-Trilogy ... 505&sr=1-1
I believe it is better than the previous "OT" unaltered release from 2005.
It has the original theatrical versions in widescreen (Even A New Hope has the original crawl sequence without the "Episode IV" etc...) also it has the "updated" versions released for the first DVD release from 2004.
What I think is intreresting (and may become even more of a collectors item), is the last time these were released on VHS for the 1997 20th anniversary special editions, only "some" CG elements had been added, more has been done, obviously because Lucas wants his fands to keep shelling out cash for new versions. I have seen on Youtube probably at least 30 minuets of "raw" cut footage from the films (most of it boring, without any merit), but if he adds only a couple of scenes, or tweaks a couple things with CG, he could just keep altering these until he dies.
I'm actully surprised that he hasn't opted to insert Jake Lloyd over all of Hayden Christianson's scenes in episodes II & III now that 10 years have passed and he is old enough to play the part.
I have what I believe to be the definitive best editions of all the films right now on DVD, I wont be dipping 2, 3 or 4 more times into the DVD well just for Blu-ray (and a few extra scenes).
There has never been a "Scientifically Accurate" Dinosaur portrayed on any Television Show, Movie, or Documentary. Only what the human imagination can conceive, and I'm ok with that.
