Odds That We See the Different Aliens in the Trailer

So the trailer drops tomorrow, and we are all super excited! However, what do you guys think the odds are that we actually SEE the different aliens described to us over the past few months? I remember watching the two minute Prometheus trailer, and as far as I can remember we didn't see the Hammerpedes or the Deacon or Cuddles. I seem to remember only seeing the Engineers. So what do you guys think?
