This article for example is guessing the same than I think, that ending of Forbidden West fits for the story of a third game. I think it's too major thing for being just an expansion. Actually it sounds very suitable for being a grande ending of a trilogy.Im curious if Nemesis will be dlc or more likely part 3 of the trilogy... the only thing I missed was any relevant connection to FW and the Banuk Tribe/outcome, which I really liked - other than that I just loved it ^^
