This is for anyone who wants to know if the "new" double-dipped Spiderman trilogy on Blu-ray has any new content or upgrade.
The answer is yes and no, most yes to Spiderman 2/2.1.
Spiderman 1: DTS-HD MA audio change from TruDolby.
Spiderman 2/2.1: DTS-HD MA audio change from TruDolby. It does appear to contain most or all bonus materials from the DVD. On the box, it said to include 3 commentaries, Blooper Reel, Hero in Crisis, Making The Amazing - A 12 Part Documentary, Ock-Umentary: Eight Arms to Hold You, and VFX Breakdowns.
Spiderman 3: Same TruDolby and Uncompressed PCM. Movie disc only.
Plus Ultraviolet copy and $10 movie ticket for Amazing Spiderman.
Update: I'm completely incorrect about Spiderman 1. From IGN:
