Well that made it pretty damn clear that there's an alien-style threat in this movie, even if it's not the xenomorph itself.
I thought this was a sidequel of sorts to Alien? I know we get to see more of the space-jockey race (and I get a strong Larry Niven vibe from those guys) and they're looking like the bag guys in this one--so far. And it looks a variant form of the Xenomorph eggs and embryos. Maybe the Jockeys bio-engineered the 'morphs?
