Nowadays, as far as I'm concerned, if it isn't announced or addressed then odds are it won't be included in the launch game if at all. I don't know exactly why campaign theatre hasn't been a feature these past two games but oh well. My enjoyment going into the campaign with regards to narrative and gameplay won't suffer because of its absence but replayability certain will. That was the case with Halo 4 having a campaign I've played little of since my first complete playthrough.
