This will most likely take place during the past and not the future. If you think about it Riply and crew of the Nostromo and the whole plot of Alien took place in the future. This will take place in our time as the past or sort of prequel I bet. In Alein there is evidence of a possible preditor. Remember the Derlect? The ancient spaceship the Xenomorph was found in where Kain was impregnated by the creature? Well before they entered into the egg chamber of the ship there was a petrified creature in the center of a huge control room. In many ways it looks like a Preditor that was impregnated by an alien. Which could mean that the Preditors are not only bounty hunters but scientists which supports your claim. And the Preditors have large ships that can be centers for holding expieremnetal specimens from uncharted worlds such as the Xenomorph. Now here is the conceptual art work done by Giger of this petrified creature that was found in the Derlect in Alien. Could this be a Preditor? And if so could the Derlect be directly linked to this movie? Like they find the Xenomorphs on the same world and then the Preditors capture thousands of eggs and hold them in their ships but something horrible goes wrong and the Aliens infest the Derlect which will eventually be discovered by the Nostromo astronauts later in the Future. Thus resulting in whoever wins we lose. What if this movie takes place on the Alien's home world and not earth. Thats a scenero. It would explane on how the ship got on the world in the first place before it was taken aboard the Nostromo.
In a lot of ways this looks a lot like Preditor technology to me at least.
