Another Alien Suit?

I was watching one of the three pre-teasers released before the big teaser. What is that in the corner? I thought it was set equipment but at closer look, it does not seem to be that. Not the human crew suit, too many metallic plates. Doesn't look like the Space Jockey's. Too clunky to be the Blue Humanoid's. Another party crasher?
