The three Spider-Man movies will be re-released on Blu-ray with new “collectible” slipcovers (“O-ring packaging” in industry lingo) on June 12. All three include an offer for a free movie ticket (up to $10 value) for The Amazing Spider-Man, out July 3, as well as an UltraViolet digital copy. Other than that, the bonus features are the same as previous Blu-ray releases, with the exception of the first film.
As the press release has it,
The Spider-Man Blu-ray includes two never-before-seen bonus features … “Spider Sense Trivia Challenge” — Rise to the ultimate web-slinging challenge as you test your Spider-Man movie knowledge in this trivia game. Do you have the spider sense to achieve the highest score? “The Spider-Man Cutting Room” — Create and share your own video using clips and music from the movie!
Additionally, Spider-Man 2 “includes both previously released theatrical and extended versions of the film, with additional footage and fight sequences not seen in theaters.” This Marvel website post has the full list of special features.
