Just wondering.
I doubt it. I’m sure they’re saving that kinda -Yoink- for Halo 4 next year.
But Microsoft’s the publisher. They got over a billion dollars. 
I would imagine they’re going to advertise it quite a bit, but probably not near as much as Halo 4 will be advertised.
I always love the live action stuff but I think the earlier poster is correct in saying we probably won’t see any. Instead I foresee some CGI based commercials.
Halo CEA is made for the fans how 343i said. Every fan knows that there is coming a remake of Halo CE on 15.nov. They don’t really need to advertise it.
