Uh, spoiler I guess for anyone who hasn't heard the leaks...
The chorus' vocals are SLIGHTLY different, the background voice (Tony Williams?) is more prominent than on the radio/iTunes version. Sounds good. The intro is longer and there's some chanting noises throughout that I wasn't really able to make out.
Obviously has the "LOOK AT YA" samples too. Ending is the same as the one in the movie with the epic distortion.
