6 Star Wars DVDs in the Fall

Posted By Joshua on June 5, 2005
According to sources for
ComingSoon.Net, we'll be seeing 6 different Star Wars DVD releases on November 1st of this year. It looks like you can buy the final movie separately, buy the prequels together or buy all six films in a complete set. Whether or not this is the "definitive release" of the complete saga is unknown, but we can sure hope for a pile of new extras. Here's the list we were given:

Star Wars Episode III: Revenge of the Sith (Widescreen) 11/1
Star Wars Episode III: Revenge of the Sith (Full Screen) 11/1
Star Wars Episodes I-III (Widescreen) 11/1
Star Wars Episodes I-III (Full Screen) 11/1
Star Wars Episodes I-VI (Widescreen) 11/1
Star Wars Episodes I-VI (Full Screen) 11/1
