Memories of Reach Teaser (confirmed infection!!!)

Hay everyone,
Recently a teaser traler has been revealed for the Memories of Reach update.
In the traler you see a spartan with a shotgun running around a new map with some Reach armor, then the screen flashes green and you see a spartan in Emile’s armor, except there is something different. The armor is completely green and he is equipped with an energy sword. And then you see him chasing after Spartan #1, and I don’t know about you but that seems like infection to me.
But why take my words for it when you can watch it yourself:

P.S. The anoncer clearly says infected at the end, but I don’t know if that matters.

I know I can’t wait. After all infection is my favorite gamemode

the trailer also shows armour based on the mk IV EVA, Scout, Air Assault and Grenadier armours from Reach.

I need my EoD armor back. I’ve used it since Halo 3…
