20th Century Fox only has a piece of SW and ESB, right? Wonder if that also goes for the documentaries, and explains why the later RotJ docs are not there. For instance on the old VHS releases there is a 20th Century Fox logo on SW and ESB but not on RotJ. It seems to me that this blu-ray set is predominatly made up of Fox centric material.
It's also interesting that there is no video from CV where they set up a booth to record fans talking about SW. (think this has also been at other comic-con like events) Maybe they're waiting till after the PvsG doc to get physical release.
