Do you guys think the halo 3 map "Epitaph" or "citadel" has anything to do with halo 5 ? It is surrounded by desert (like in the trailer) and it is Rumored to be the grave of 032 mendicant bias . (Who may also make an appearance in halo 5)
EDIT: Im taking about the location, not the maps

Well the Hologram on Epitaph is one of the forms MB took at one point in time. I remember it either being stated or highly implied to be him. Ehh. I had the idea of Going back to the Ark, Finding MB, and then looking for the Absolute record. But i am not too sure about it anymore.
