No time travel will be in it. At least I doubt it, because the voice in the back echoing Cortana is the Gravemind, remember him? He is probably the one who was holding Cortana back while she was in the Mainframe of High Charity. And most likely, since none of us really knows his true power, the Gravemind is probably able to send brief, distorted communications in which we hear in the trailer. Most likely the Gravemind is like the first flood to be created, and most likely he was created or found and experimented on by the Forerunners, then he began taking over the Halo and used the flood to fight the Forerunners, they activated Halo, killing them like it was said in H2, and left the Gravemind there. But I dont really care about yours, mine, or anybodies theories because noone knows except Bungie. But its fun making shyt up huh?
