What's sad about having to buy the 2004 re-dos, just to get the OOT versions, are all the errors in the lightsaber color-correction. (i.e. Luke's green saber during the training remote scene and Vader's fashionable "pink" blade in ESB & ROTJ)
Well, this may prove to be exactly what's released, but on the other hand this is George Lucas- I give it a 75% probability that these versions are further edited. I don't expect anything major, but I have the feeling the Tie fighter "green force fields" in ANH and even more so the afforementioned lightsaber discolorations will both be edited/fixed.
Personally, I want to see the original version of ANH with all
of Biggs' scenes, and Luke witnessing the opening scene battle at a distance with his macrobinoculars, re-added to the movie and all the original cheesy special effects; the DVD version of ESB as-is (although they might edit the new Emporer hologram to be a little shadier and harder to see quite so clearly- it gave him intrigue); and a version of ROTJ just like the DVD version sans that wretched SE song scene, and with a new, modified/refilmed Hayden ghost- Hayden Christensen with a less creepy/more warm smile, and make up/hair color changed to make him look a vague amount older.
And those versions will never, ever be made.
