While I think some of the claims about secret motivations are dubious, as well as the 'please no LGBTQ+' stuff being... icky... I think Amnmaat is correct that adding Male Viera and Female Hrothgar would STRONGLY signal an intent to keep FFXIV going and prioritizing keeping it good. The lack of them doesn't say the opposite though, we have known for a long time SE doesn't prioritize resources to XIV despite how much money it makes them.

I think it would be absurd not to notice XIV is in a good position to be the fabled 'WoW killer' MMOs have been chasing for over a decade because if you do that you make all the money, and invest harder into it on multiple levels. In a way they are doing that: reworking ARR indicates they think the game will live long enough the new player experience will matter, and potentially sets them up to extend the trial to all of ARR without turning people off. So I definitively think XIV has at LEAST 2 expansions left. The question is how SE will try to maintain their dominance of the MMO market, and new races are sign of growing prioritization of the game, more than if XIV is gunna die.
