What I find a bit time consuming here is the MMO:S that I am at least slightly interested in:

Baldurs Gate 3 is going to be released in August 2023 and perhaps it will keep one interested in it still early 2024 but even from early
2024 it is long wait for some of these MMO:S indeed.

Throne of Liberty aka Lineage 3 MMO. Unreal 5 engine and the only fantasy MMO game (that interest me) I expect full release in 2023. Unknown what will cost etc. slightly interested. but like calling it Lineage 3 instead. Release date: During 2023.
Voluntary PvP but my issues is with no classes and then PvE zerg farming bosses in outdoor dungeons and raids not balanced. Well and guess more or less buy to win elements could be included. Anyway beautiful game no doubt with Unreal 5 engine. In huge fights Lineage 3 reduce automatically graphics from what I have heard.

Ashes of Creation MMO with Unreal 5 graphics.
The ultimate PvP world. On downside not only voluntary PvP. Huge PvP battles possible example 500 vs 500 players and an Dragon in that area that can affect outcome with Unreal 5 engine and plans to not reduce graphics interesting to see how they manage to do this? We have had really big fights yes, but yet not shown 500 vs 500 players.
Hardcore old school type of MMO... Epic Raids and Dungeons instances. Slower levelup and progress.
Well not pay to win and subfee.
Release date: My guess year 2024 or 2025. During 2023 I do expect ALPHA 2 to come out and then lots of more information.

Dungeons Dragons MMO (Neverwinter ONLINE exist, but it is outdated) with Unreal 5 graphics. Developed in USA.
Release date?: Unknown Guess 2025-2028. Even the name is unknown for this MMO.

Riot (company developer of League of Legends and n other successful games) upcoming MMO. Unreal 5 graphics.
PvP will certainly be included more or less. Very unknown project, but huge budget. Will have Raids and Dungeons.
Release date?: Unknown Guess 2025-2028. Even the name is unknown for this MMO.

Unreal 5 only better graphics? No it runs better system performance. Despite excellent graphics better system performance for big /huge fights. It runs much better then Ray Tracing yet manage to look as good. It runs better then Unreal 4 engine huge fights. One of the effects that Unreal 5 manage with other technology do what ray tracing can do and with much less system requirements.
