One thing that occurred to me the other day: if they're following the Fire and Stone formula, that means four 4-issue mini-series. That being said, they've only solicited one series, Predator, so far, so they might be releasing this one series at a time, rather than all together like they did with FaS. That means it might take well over a year for all of this to come out. 16 months from March 2016 is June/July 2017. That's just a few months before Alien: Covenant is set to come out. That makes me think that the Prometheus or Aliens leg of this could be getting the "Official Prequel Tie-In" treatment.
TL;DR: this whole thing could wind up tying in closely with the upcoming movie, which potentially bodes well for it having a meaningful story.
