It's hard for me to keep up with everything that is going on with this project. At first I didn't realize what the purpose of a 2.0 version would be since to my eyes (which were clearly out of whack) the 1.0 was a perfect restoration. But i must say the pictures you posted really put it into perspective!
I found out about this project when Star wars was up to 2.5 and the sequels were both 1.0. I saw the documentary at the same time and assumed that that process described was basically the same for all three.
Are the sequels just now getting the blu-ray footage and that's the reason for the quality jump?
Also may i ask since 2.0 is out and looks wonderful, what is to be accomplished in a 2.5?
Sorry if this is all repetitious to people who have been following this closer than I, but I was curious.
