no. Life vs Death has always been the point. Or rather, "stop fighting over petty bullshit, humans, because nature will kill us all if we don't do something together." That's pretty much the thematic core of the series. I'm sure we'll get bitchin' lore but they're ice zombies and they're coming to end all life.
the fact that there are stories of that lady other seducing the og night's king and that they somehow made a deal with craster for babies makes it seem like they can be reasoned with. wouldn't surprise me if the series ends with a truce of some kind.
i've watched a bunch of preston jacobs videos, and while many of his conclusions are wild as fuck, he does make one point that is very difficult to argue with, based on tons of gurm's work: being anti-war is his big thing, so it seems odd he would end his magnum opus with a giant battle between good and evil (or life and death).
