On a serious note, imagine one of the OneD&D playtest packets that get released during 2023 was ANOTHER Psionics UA.
I wouldn’t be surprised.
Playtest Packet 1 explored Arcane, Divine, and Primal Spell Lists; I’d imagine there would also be a Psionics Spell List and are holding that closer to their chest because it’s not core to the 2014 PHB.
If say, Oath of the Ancients Paladins get access to the Primal Spell List and Divine Soul Sorcerers get access to the Divine Spell List, then perhaps Great Old One Warlocks get access to a Psionics Spell List.
Seems like a very simple way to resolve it. And then at least one Arcane Traditions might become partially Psionic - School of Enchantment is what I’m primarily thinking of; Illusionists feel more classically Arcane than the mind-bending Enchanters. Meanwhile School of Divination may become our Mystic Theurge with access to the Divine Spell List…
Just throwing things out there. I could see this as a very quick and dirty way to do Psionics. They’d still need a non-bookish but Int-based Psion casting with special rules; I could still think they could do that if classes are let loose from Key Ability Scores. A Psionic Magic Sorcerer with Spell Points and Sorcery Points as a fused pool and using Int instead of Cha and access to a unique Psionics Spell List is essentially all I want from a Psion. Aberrant Mind is almost there but it only does Psionics sometimes and it still has spell slots and it still uses Cha (so it’s more of a Gooey Wilder).
They treated Artificer as an afterthought that was still mentioned in Packet 1 (i.e, Bards, Sorcerers, Warlocks, and Wizards, as well as Artificers, draw from the Arcane Spell List). That suggests that only the original 12 classes will be in the 2024 PHB, but they’ll recognise Rules Expansion as cooperating with the new rules. So we wouldn’t have a replacement for Aberrant Mind or Psi Warrior or Soul Knife. Not would we have Artificer or Psion as separate classes in the new PHB. But we might get Psionics as a new subclass of a core class, whether as a Wizard that doesn’t use a spellbook or a Sorcerer that uses Int.
It’s also very possible they Psion will not show up until Dark Sun, and then get reprinted a la Artificer in one of the next Rules Expansion books (perhaps even Book of Many Things; we’re due a Rules Expansion 2 box set to combine Fizban’s, Bigby’s, and Book of Many Things).
