I don't think so... in the Nentir Vale, the gods need to stand together, even the evil ones, because the forces of the primordials outnumber them by a wide margin. I remember some sourcebook that states that the gods, even the evil ones, grudgingly accept each others because that god that you kill today, is the one who may have saved your life when the primordials return (and they will return, or something even worse may take their place). So, the betrayal of the evil gods is really a dumbed down version of the gods of the Dawn War.
But I may say that because I'm a bit tired of the bored cliche of good vs evil that's so integrated to D&D.
I'm glad we never saw Mearls' Nentir Vale. Too many unnecessary changes for my tastes.
