Precursor structure in Spartan Ops?

In this pic http://i.imgur.com/rlkcM.jpg, that structure really doesn’t look like any familiar Forerunner structures we’ve seen so far. I believe that it could be a Precursor structure, which would be so shocking and exciting. Hope this happens, what do you think?

Very cool. I haven’t seen that in the game.

What chapter were you on?

It’s from the trailer of the rest of Season One of Spartan Ops at the VGA’s last night.
