other covenant in halo 4?

I was thinking, elites have already been confirmed. What other covies are in halo 4 then? My first guess would be brutes, but how would they be different in halo 4? I think the brutes would be more savage and elites might be allies, anybody else have news or guesses on this?

Grunts and Jackals are there. The Elites and Brutes together just wouldn’t make sense.

I’m sure Grunts will make an appearance.

Grunts are confirmed too.

I meant elites as player allies, but seeing recent news I see Chief fights elites.

well from what ive seen, Elites and atleast Grunts are united against humanity. i believe that maybe the covenant will be split with the Seperatists (Elites, Grunts, Hunters) vs. the Empire (Brutes, Jackels, Drones). thats just what i think based off of the behaviors and loyalty of the different species. all i know is Elites are part of (a) Covenant. and Elites and Brutes hate eachother, almost to the point of Rascism. So im sure they wont be united
