There's a lot we have seen already. It opens with the same shot of the Prometheus flying towards the planet but we see a new shot form the interior of a man standing above a huge glass window (I assume the front of the ship). Next we see shots of the prometheus on the planet and the buggys driving away from the ship followed by the huge dust cloud engulfing everything. The red lights from the teaser trailer come from spherical objects that one of the human characters throws up into the derelict - some kind of scanners?
We also see the guys with guns firing at another blue suited crew member who is slamming someone against a wall ( I assume) on board the prometheus.
The best shot at the end is one of a ship (prometheus?) taking off with the derelict flying in the distance, it looks like they're chasing it.
Thats about it as far as I can tell!
