wow this is huge. my buddy got home from school and told me that he heard about an easter egg in the final epilogue scene with sgt johnson. we played the last level and beat the game. after the credits when the epilogue comes up, hold Left on your Right analog stick. when the part where Vergil goes to light sgt johnson's cigar, the camera will shift to the left (because you are hold the analog stick) it will show Buck and the Monkey easter egg from Halo 3. Buck will pick something off of it and go to eat it but right before he puts it in his mouth the scene ends. lol it is pretty funny to watch.
