Could the below video posted by MindKiller649 be Linkin Park's new song "New Divide" for the Transformers 2 soundtrack? The validity of the music, which is instrumental, is unknown as the single is scheduled to be officially released on May 18th to radio stations and iTunes. I guess if it gets yanked by Paramount for copyright, we will know then.
Update: Well that was quick. It is not New Divide from Linkin Park. Not really sure what the point is. I guess people where taking the few chords from the trailer and extrapolating. Only because of the comments I am not deleting the entire post.
