Predator 2 was first released on DVD in the UK in 2001 as part of the Predator 1 & 2 Boxset. I don’t think it was ever released as a singular DVD until 2004. The US version had a couple of featurettes which were missing on the UK version.
The Predator 2 2-Disc Special/Collector’s Edition Set was released in the US in January 2005 and in the UK in April 2005. This has lots of new featurettes but the US version has the addition of the theatrical trailers and TV Spots while the UK version does not. It was re-released in the UK as Predator 2: Definitive Edition in September 2007. It was re-released again in 2010 with the same Blu-Ray art but I don’t think it included any extras.
The Predator 2 Blu-Ray set was released in the UK in November 3, 2008 and June 9, 2009 in the US and includes the same special features as the DVD sets. As before, the US version appears to have the various trailers and tv spots while the UK version does not. A Predator 2 Limited Edition Steelbook Blu-Ray set was released in the UK in 2013 which included a DVD copy too.
In August 2018, 20th Century Fox released the Predator trilogy on 4K Blu-Ray for the first time. The 4K version of Predator 2 cannot currently be bought on its own and must be bought as part of the Predator Trilogy 4K Set or the Predator 4-Movie 4K Set. The commentaries are on the 4K disc but you also have the regular Blu-Ray with all the featurettes.
Predator 2 has been released as part of many DVD and Blu-Ray boxsets over the years. The first release in the UK was in 2001 on DVD which included the single disc versions of Predator and Predator 2. A boxset was released in 2004.
To promote Alien vs Predator in 2004, Aliens and Predator were re-packaged together as a 2-Disc or 4-Disc Set with a bonus disc with a behind-the-scenes AvP featurette. The latter set also had a movie ticket to AvP and some art cards.
A 4-Disc collection with Predator and Predator 2 was released in 2005 which included the special editions of both Predator films.
Japan saw the release of the AvP Monster Box including every Alien, Predator and AvP film. In 2006, a Deluxe Predator Head sculpture and DVD set was released in Japan and Europe which included both Predator films and AvP over 6 discs.
Predator 2 was then collected in 2008 as part of a 8-Disc Alien vs Predator: Total Destruction Collection compromising of every Alien, Predator and AvP film at that point. The Predator Quadrilogy was released in 2008 including both AvPs and both Predator films.
Australia and some European countries got the Alien/AVP/Predator Ultimate Annihilation Set in 2011 – a 11-Disc Set including all Alien, Predator and AvP movies, as well as art cards and a booklet. After Predators was released, there were a few Blu-Ray boxsets including all three Predator films. When the movies moved to 4K in 2018, you could also find the movie as part of a Predator 3-Movie or Predator 4-Movie 4K collections.
