Well, let me put it like this, who/what will we be fighting in Halo 5 and 6? First of all, what factions are there? Let's see if I can list them all: Precursors Gravemind Flood (listed separately since I'm not sure who will be contolling them) Mendicant Bias Offencive Bias The Librarian Bornstellar Ur Faber The [i]Storm[/i] The ONI... Mysterious crashed spaceship Cortana? Automated Forerunner security systems under a monitor (EX: sentinels under 343GS) Those were all right? The two who are already introduced and kind of unresolved are [i]the Storm[/i] and the Prometheans. I'm pretty sure they'll introduce something new, since basing a new game on two known enemies would be considered dull by many. But will it be the Flood? Halo 4 ended [i]back on square one[/i]; Chief's again in touch with human forces. [b]Where will it go from here[/b], will Earth or a human colony be attaced, or will the Infinity take the fight somewhere? I'm leaning towards the latter, and that makes it very hard to predict. There's no ongoing action, so whatever scenario they'll find themselves in, it has to be one where they encounter action pretty fast, there would have to be action of the first mission. That's unless the formula is changed, or if the action starts in another media. Where will they be going then? Will they find the coordinates for something, will this be when MB and OB are reintroduced, perhaps one or both of them will provide for new enemies? As it is now we have a lot of factions, a lot. The question is who'll be friend and who will be foe? [Edited on 12.23.2012 12:27 PM PST]
