This is just an alert since there seems to be some confusion about a trilogy release with the original unaltered versions along with the special editions vs a trilogy set that only contains the special editions and no copies of the original unaltered versions.
The reviews for both sets are merged together... that is why you are seeing people claim that it has the original unaltered versions, and people complaining they do not. THIS set that I specifically clicked on to make this comment on is on the 2004 release which DOES NOT CONTAIN THE ORIGINAL UNALTERED VERSIONS. The box image is silver and has Darth Vader's mask on the box. This set ONLY contains the SE along with a 4th bonus disc of making of features and trailers and a sneak peak at episode III. If you want the trilogy set that contains both the SE and the unaltered versions but no bonus features, make sure when purchasing from Amazon, that the picture is a picture of Darth Vader and Luke clashing with light sabers and the box has a lot of blue coloring. It also says IV V VI along the bottom. Scroll down to DVD info and it should say release date: 2008. THAT is the version you are looking for.
If you place an order on the Trilogy with the Silver box with Darth Vaders mask on it, you are going to get the 2004 release of the trilogy and that's probably not the one you want... This review is going to appear on both sets though... So make sure before you buy, that you are on the correct trilogy page. Check the picture. Check the release date.
There are plenty of reviews of the actual product so I'm not going to go into that. Just wanted to clear up some confusion.
UPDATE 11-23-15 There are no longer copies available from retail that have the original cuts included anymore. They're out of print. There are no bluray editions and no current editions with the old cuts. You can still find the ones with the original cuts but be prepared to pay a hefty price.
