Both sets include tons of brand new special features such as documentaries on the movie’s production and legacy as well as unique sneak peeks at the upcoming threequel! Personally, I’m most excited to see the Studio Stories and Paths to Pixar featurettes. You can check out the full list of features here, but before you do, watch the exciting trailer:
Toy Story and Toy Story 2 (click to pre-order, each sold separately) will be packaged as a Blu-ray + DVD Combo Packs but also come in DVD variations. Like Woody says, "If you don’t have one, get one [on March 23rd]!"
