I'm pretty excited about it. Moreso since I caught the SW documentary on A&E this past Sunday. I think it was called "Building of and Empire," or something like that. It wasn't too clear, but I believe that it's part of the DVD set, too.
What was interesting was that I thought I knew most of the "behind the scenes" stories. However there were a bunch in this doc that were just outstanding. One of which was hearing David Prowse's voice saying the lines for Darth Vader, which I had never heard before. It was outstandingly inciteful. And it made me very glad that they went with James Earl Jones' voice-overs for the Darth Vader character.
There are lots of other great stories like this in the doc, too. I'm really hoping that they're including it on the DVD because it'll make it that much more of a collector's item.
