Is 343i going to have a booth at pax prime 2012? If they do will we be able to play haalo 4?
I don’t think they have said anything official about PAX yet, but considering it’s located right next to their studio, I bet they’ll be there with a playable version of the game.
After all, they did make this little thing called HaloFest there last year. 
I’d say they will. They want to get word about Halo 4 out as much as they can and as much advertisement as they can to get new Halo players in and show off their amazing game. I’d say they will make an appearance there, it’s in no way confirmed though.
Im pretty sure they will. They are stationed in Seattle so why wouldn’t they. I know im going to pax12 though >:D
