I have heard from a lot of people who say they know for sure he's lying and has all these pristine copies of the saga just laying around in his basement, but it seems like a whole lot of assumption to me.
I really think this is one case where the "dog ate my homework" isn't just a huge lie.
I think that's part of the reason he didn't originally entertain the idea of O-OT on DVD, because he knew the best he could do (without hiring Nasa to ressurect the original picture quality of the film from a bunch of worn out prints), was to use one of the previous home video release masters as he has. I don't think he wanted to put out a DVD with a movie on it that wasn't Anamorphic in this day and age. I could just picture Jim Ward begging him to just let them do it, and Lucas saying: I don't think they'd want what I can give them".
Now if it's really not a big deal, if there really is a print laying around that he could send to a lab for a day and be done with it, then I think it would be in poor taste for him to not do that.
Is there anything beyond speculation (or anonomous people who conveninently happen to know for a fact but can't reveal how they got the info without occupational rammifications), to say he's really lying about all of this?
