I don’t know. As a fan of the genre there seems to be renewed interest from some very grass roots developers. I would have agreed with your take in 2020, but in 2023 we have announcements of:
the Riot MMO
Ashes of Creation
The Ghost studios MMO
These are all still in development, some still in the very early stages. But I would say there appears to be renewed interest in the genre by developers. These projects are major investments by industry veterans. There is more hope for a major new game.now than there has been in the last decade.
