The reason I say this, is because a while ago when they were showing trailers, there were cutscenes in those trailers that are not in the game anywhere. Specifically the cutscene where you meetup with that awoken hunter (looks like it's on earth) and he's pointing a hand cannon at you, saying "out here in the wilds this is how we say hello". This either means this whole segment was cut entirely or there is more story/cutscenes to come in DLC... which I really hope isn't the case honestly, because that means they literally cut off potentially vital story elements for DLC, thus leading to an incomplete product at release.
