What exactly do u guys think 343 will talk bout w/ Halo 4?
Reach TU, Halo CEA and Halo4, of course. 
I hope they talk about the engine and a little bit about MP. I see that their audio director will be there so I assume they will speak on the sound/music in the game as well.
I think Halo 4 panel is going to be tight-lipped, but still open to some questions. I’m pretty interested in the Chief’s next adventure, so I would like to know a little bit more about what Halo 4 is about.
