dandan
With all due respect, you have no idea what you are on about, Scott has stated "the keen fan will notice strands of alien's dna", prometheus will have no xenomorphs directly resembling the one from scotts alien film as such regardless of size, more like just a few small traits as a nod towards the creature. I think we could very well see the space jockeys, but scott and fox are trying to distance themselves from the xenomorph as it's been over exposed by too many films from milking the cash cow of the alien franchise. Space jockeys, have not yet been explored and if anything prometheus will feature them, so with all due respect give it a rest.
