I have no idea. I kind of want to, but I have nice looking bootlegs, so what's the point? I might pick up Star Wars so I can have the version without the "New Hope" title on it. Also, it would look better than my bootleg, and noticably too. But ESB and ROTJ probably won't look much better on the new DVD's, so no point really.
If I had the money, I'd get all three. But I don't. Maybe someone can help me make up my mind..
