Aren't Blu-ray disc releases supposed to contain more?
In a story from DVD Town, it seems that on the Spider-Man: The High Definition Trilogy release both Spider-Man and Spider-Man 2 will contain no extras.
Both of those titles will offer Dolby Digital and Dolby TrueHD audio.
Also, Spider-Man 2 will be recently released the 2.1 version. The normal version will also be available "through seamless branching."
