The mmo genre is a collection of people continuing to play FFXIV and WoW while desperately thirsting for something new that isn't being provided.
I used to have Blue Protocol (cancelled) and Ashes of Creation on my radar. Ashes has dropped off my interest because it's designed around pvp in a way that will not retain players as the losing players will not have fun.
The only one on my radar for the future right now is Stars Reach, which is being developed by the dude I consider responsible for Ultima Online, Star Wars Galaxies and Everquest 2. If there is anyone in this industry that actually seems to understand mmo communities as a social phenomena it seems to be him, even if he is a little techbro brainwormed at times. The game is basically trying to be Noita style interactions but 3d at mmo scale with all the mmo economy bells and whistles you'd expect. It is the first thing in a long time that I've seen which is genuinely trying to do something new that does not actually already exist and that alone is genuinely interesting.
Everyone is really really thirsty for new mmos so any slop released gets MASSIVE then drops off hard when it doesn't meet expectations, typically korean mmos filled with the most grindy and obnoxious systems in existence. Lost Ark's player count chart illustrates this well https://steamdb.info/app/1599340/charts/#max or I guess a more recent example would be Throne and Liberty: https://steamdb.info/app/2429640/charts/#max
