NO. Keep your metaplot 100% away from my game. That is the single most likely thing to make me stop purchasing material. It did it for the old World of Darkness, it largely did it for 2e for me, just no. No metaplot at all.
I would basically start laughing like The Joker if, in 2022, WotC decided the way forward for D&D was a 1990s World of Darkness-style metaplot.
I mean, good god.
Sadly it's not outside the bounds of possibility but good god. I definitely concur that it would be a truly wild bad decision. Especially as a metaplot necessitates protagonists, and if you don't specify those protagonists, they essentially become whatever major NPCs are tied up in the metaplot.
It seems obvious, the current plans for 2024 core lack Psionic.
Which is probably smart. If you want to do psionics in a way that works, you don't want to force it into every game as a default, and you don't want to do it in a way that's more oriented towards making people hate or dislike psionics go "UGH OKAY I GUESS", rather than making people who are neutral or like psionics go "whoa cool!".
Even if WotC intend there to be a "Psionic spell list" (which, I personally hope not, it's 2022 and the game has been out eight years, people can cope with a new system, they really can), WotC would be smart to contain that to a future book on Psionics (possibly as part of Dark Sun, possibly something else).
If WotC were brave rather than smart, sure, drop Psionics into the PHB and have Mystic proudly sitting there as another full caster (with spell points not slots, I absolutely beg you, WotC lol - it's easy! Your system does it well!), but WotC aren't that brave.
