Yeah, it's probably symbolic of the Engineers being the creators of mankind. It's definitely the variant I'm ordering, unless an even cooler one comes around.
Hopefully this time around the story focuses more on the mysteries of the Prometheus side of things, rather than Engineers pummeling people. Not that that can't be part of the story, but it would be neat if they explored some aspects of the Engineers terraforming (Tartarus and LV-223 are both jungle worlds, so maybe we're seeing a pattern of what type of atmosphere the Engineers prefer) or had one of them interact non-violently toward the human characters.
