Not saying I disagree with you, but what happens if there is proof that he does own pristine prints? Would he be a liar then?
All I think he's doing (really) is protecting the product to which he feels is his vision of the Original Trilogy. I have nothing against that.
Either way, if he does have the pristine prints, he's still not going to spend money to remaster them for DVD. Not going to happen to the "workprints." And you can forget about HD dvd for a while. It took Star Wars 7 years to reach DVD. Expect the same with HD.
