My collection of Alien and Predator DVD's is a bit odd, I lived in the UK for a few years and have bought the boxes but then went and gave the actual DVD's to a friend and kept the box! I'll give you the rundown - (click the thumb)
From left to right -
Pred Ultimate Hunter Blu-Ray (I don't have a player yet but I got it for $15 with a free Predators ticket!)
Pred Region 2 original box set box, contains Region 1 DTS P1 and bootleg P2 with original artowork from the VHS
Pred Region 2 Special Edition box, contains original Region 1 P2 release plus Region 4 P2
Pred Region 2 Definitive Edition (non steelbook sadly)

Ya I'm kind of a nerd, I should probably get rid of some, especially the AVP! If anyone would like more pics of a certain DVD just ask!
