November 21, 2012@nostromo: its best to think of the "3D blu ray set" as the "4 disc collectors set". Saying that the aforementioned set is the "3D set" has (understandably) confused folks (especially someone like myself who avoids 3d like the plague...i hate 3D, but thats a different discussion). Everything in the 4 disc collectors set is 2D except for one disc that contains the film in 3D. here is the disc breakdown:
disc 1: (blu ray) theatrical Prometheus in 3D
disc 2: (blu ray) theatrical Prometheus in 2D + all of the deleted scenes and some other goodies (weyland files, complete viral videos etc)
disc 3: (blu ray) "furious gods" documentary in 2D (plus a bunch of archived artwork and other goodies)
disc 4: (dvd + digital copy) theatrical prometheus in 2D (standard definition)
as you can see, the 4 disc collectors set has everything. If you can get the set for a good price (and amazon has had a smoking deal going on for the last day or so), there is really no reason to get any of the other sets. Im very pleased with every aspect of the 4 disc collectors set. Also, the documentary is fantastic...one of the best/most thorough docs ive ever seen. Go buy it...now...before the price jumps back up. lol.
