There's some great new footage in this but I'd rather have not seen some of it, as it felt a bit spoilerish. Also, I dislike the Jockey's arm being so short. Why is it so short?
This shot makes me suspect that Vickers is the second android. Remember that early concept that Ridley Scott had for 'Alien'; where Ash would wander the corridors of the Nostromo, whilst the human crew were in cyro? The shot above instantly recalled that for me.
