I really don't watch bonus features or documentaries more than once these days, if I even bother to watch them at all. So if the new set has deleted scenes, I'll rent them just to see how they are. But odds are, someone will upload them to youtube anyways. (not that I would download a copy to my computer).

The footage might be reincorporated into other fan edits as well. However, I am not collecting every star wars bonus feature out there so I don't see a need to own everything for a personal repository. If someone else wants to do that, fine.

I'm not buying the movies unless the originals are fully restored. I have the 2006 dvd's, I don't need more videos if it's just the same stuff I already have.
