They are awesome! I really love them. Here's what they have
Disc 1

Theatrical widescreen version) has a Fan commentary, photo gallery, facts and trivia about the movie and more
Disc 2 (full screen version) has All-New Featurettes: "Death of Optimus Prime", "Cast and Characters" and "TRANSFORMERS Q&A" with Nelson Shin (Director), Tom Griffin (Producer), Joe Bacal (Producer), Flint Dille (Story Consultant) and Sue Blu (Voice of Arcee) US and Japanese toy commericals, Activate Autobot City Trivia Game (DVD-ROM) and more
Both disc have Easter eggs. It's really awesome. I was sitting at home watching it this morning because I'm sick and have nothing else to do. Do you have the movie on DVD yet, Reaper?
