SAW and Promethean Minigun?

Looking at the Warzone trailer again, at 0:38 you can see the blue Spartan drop a SAW when he’s being assassinated. Also, at 0:41, some sort of Promethean construct, not looking entirely like a Soldier, with some sort of Promie minigun.
Im needing out a bit too hard right now, I know.

We all are brother the hype is real.

Plus you can see a player holding what looks like a Saw at 12 seconds as well.

Also it looks like the promethean ships will be flyable, or at least by AI.

So is Warzone: Blue vs. Red vs. Covie vs. Promethie?

Perhaps the promethean mini gun will be the forerunner detachable turret?
