People want to be in on the ground floor of the new hype thing. Then they leave. That's what New World proved, its colossal dropoff in active players and revenue wasn't entirely because Amazon killed some golden goose. Anyone trying to say "people want new MMOs" is probably coping about that surely the new MMO they want to not fail is going to survive.
New Thing Hype works for a couple years to be sure. And then you run into the content wall and learn that by playing a more established MMO like FF or WOW or ESO or GW2 you get decades of "new content" all at once.
