I see the finally added some actual online exclusive content for DVD owners:
(Previously all we got was a list of cast & crew and brief plot synopsies for the movies... the rest were direct links to Starwars.com and the usual databank entries on that site).
I'm not a huge fan of "exclusive online content" but hey, it's something. I haven't gone through the stuff for Episode I & II yet and I own those. As long as they plan to keep them up indefinately I can always check 'em out later.
