Will, I think that's all theory and I also think the whole "Hunt" will not be concluded in this game. A lot of the promotional stuff is saying "The Hunt Begins." I'm not sure we are going to see it end in Halo 5. Also, I don't think that they are going to kill Chief off right after he got that "Upgrade" from the Librarian. There are a lot of questions still unanswered and killing off the Chief doesn't seem like the route 343 wants to go.
