You knew this was going to happen. If you say that you didn’t, then you’re either a fool or a liar. I just found this on StarWars.com:
Returning to store shelves on November 4th are the six episodes of the Star Wars saga on DVD bundled in convenient trilogy sets. Perfect for gift-giving as the holidays approach, the Prequel Trilogy set includes Episodes I-III, while the Star Wars Trilogy includes Episodes IV-VI.
Fans who already own the prequel trilogy double-disc releases (released from 2001-2005) and the Star Wars trilogy double-disc releases (released in 2006) already have all the content that’s available in this set. There’s nothing new in this set you don’t already have. But for friends and family still looking to fill in these gaps in their DVD collections, these sets make it easy and affordable to complete the saga.

Own the saga on DVD November 4th.
Thankfully, there is no new content. I know that there’s no way that my wife would let me try to justify buying the saga again because of a new 45 minute documentary on how Jar Jar Binks is the best character in any movie throughout history or why I should be happy that we got Ewoks in Return of the Jedi instead of Wookiees.
