I thougth the set in Austrailia compiled all 6 movies from each individual release (so it includes the oot). This will likely just be identical to the 2004 set. Which is totally pointless, the first box set is still readily available. How many times can Lucas release the same exactly identical stuff year after year? Does he really expect us to buy a movie just because it's in a stupid slim case? The 2005 set did not sell well and I hope this likewise collects dust on store shelfs. People need to send Lucasfilm a message that they will no longer buy a video just because it says Star Wars on the box.
If it had the bonus disc and used the 2 disc '06 sets with the 2004 versions corrected, then there would be at least some point to it. But Lucasfilm is way too lame for that, even someone who prefers the special editions and likes the prequels has to admit LFL has done a poor job with their SW video releases. Look at the upcoming Blade Runner and Close Encounters of the Third Kind sets.
