A bit of baseless speculation on my end but what if this ties into Predator:Hunting Grounds? Sure jungles are just kind of a thing with Predator but we know somebody is gunning for Stargazer, they show up in the last series, and both Hunting Grounds and this will take place somewhere in South/central America. We know the game will release somewhere in 2020 and the summer season would be the ideal time to release Predator content even if the book will have wrapped by May.
Maybe this is just a bunch of coincidences but Ilfonic did say they got to see things we haven't and that thing might've been this comic. Perhaps it's going to have some narrative connections to the game or that the game will reference events from this.
Even if not I'm glad we're getting another, these comics have been really good.
