Kepler, Vex, and Sundaresh

So I was rewatching the Edge of Fate reveal and noticed a little something, mostly involving our favorite (usually) bronze simulation machines.

Aside from the new enemy units, which is interesting to see the Vex sending in a new unit yet again, I noticed these Vex are the normal bronze without the Choral Vex's usual weird collars.

We do know that Maya's Vex are on Kepler, as seen in the trailer, but I am curious as to if we are witnessing the greater Vex Collectives starting to clash against Maya's Chorus for whatever the Nine have that they want. I won't lie, I am excited to see the Choral Vex again, I thought despite Echoes' flaws it was a good start to see some more Vex plots.

I am also eager to see if Maya gets more spotlight, and potentially goes into more Vex-y routes with how she handles things. I know alot of folks won't be happy to see her again so soon but hey, a character can't get better unless they are given the opportunity to!

Also I am more curious as to what exactly the Vex as a whole wants from Kepler? Maybe the microbes that allow for interaction with Dark Matter? I am excited to see!
