To me it looks like generic Alien movie number 124234234. Not very excited after this trailer. I would rather they did the actual Prometheus 2 and explained the plot about the aliens that created humans.
And tbh it's brilliant and it's incredible 1979, it's so much ahead of its time. Great movie, I really enjoyed it and I didn't even feel those 2 hours.
Prometheus is better than its reputation.

I think the Engineers have a part in the new film from viewing the one trailer. Both Noomi Rapace and Fassbender are reprising their roles, and the trailer seems to hint at a couple things regarding the engineers. I think connecting Prometheus to the original Alien could make for a very interesting film, combining the best of both... Fassbender looks to play a prominent role and from the nature of his character in Prometheus I think it is fair to hope they utilize some of that film's aesthetic.
