Hello, I just watched this http://www.youtube.com/watch?v=Wg9ILg16U9s and I believe it is not leaked because it’s 343 speaking to us. So their is music in the background, Could it be Halo 4 music? And when you see the screens where people are working at, could it be Halo 4 gameplay? Thoughts? If this is leaked I am sorry but I’m not sure and If it is mentioned before I am sorry again for wasting your time, this video was posted 8 hours ago.
Seems you’re a little late to the party.
No worries. Head to this thread where a bunch of people are discussing it
