My biggest concern about the Bard in the UA, is when they tried to streamline weapon proficiencies in all classes, harming the Rogue and the Bard. Currently Bard's don't get proficiency in Rapier, Hand Crossbow, Shortwords or Longswords, as they only get Simple Weapon Proficiency and nothing...
I think it's going back to the Bard spell list being around, there just might be more choices for extra spells, or maybe Magical Secrets is something Bards get earlier.
They're probably keeping the change Font of Inspiration, where you can exchange a spell slot for Bardic Inspiration Die.

Bring back the Elan, a mostly human-like looking race (or lineage in the way the Reborn are) that with a psionic physiology who happen to be Aberrations.
D&D also has to contend with video games now as some place where new players have their fantasy expectations from, and in many video games even the warrior types have "spells" (like a ground slam shockwave attack).
I liked the ideas that Bruce Cordell had, the only person at WotC who was really into psionics. Based on what 3.5e psionics got, the answer is basically "All of the above". The Far Realms, Victorian influenced New Agey stuff with crystals and ectoplasm, along with Buddhist (Tibetan Tulpas aka...
Or reskinning for players who want to play a Technomancer where "I load an unstable fire element bullet into my experimental multi-pistol" is simply casting Fireball as a spell, even though the Artificer covers Technomancy too.
I think the Psionic subclasses will prepare the way for a Psion class eventually. There's a given "don't make completely new mechanics" for psionic powers now in place, because there's psionic subclasses of casters like Warlocks and Sorcerers that just use spells. Then it opens the way for a...
I think it's better that the Psionic Sorcerer subclass is aberrant themed (3e had Illithid bloodline feats, so there's precedence), not only because it was more interesting than them being a generic psion replacement, but because I don't think the entire weight of psionics should be carried by a...
When they proposed to change it to the psionic soul back in some UA before it appeared in Tasha's, I rejected it because I felt it was really boring compared to Aberrant Mind. In fact most people admitted that they felt psionic soul was really boring compared to Aberrant Mind, so they went back...
Tieflings in the UA were vaguely tied to Devils (Infernal), Demons (Abyssal) or Yugoloths (Chthonic). And I think they even suggested that some Chthonic Tieflings might be descendants of Succubi or Night Hags. No direct mention of Rakshasa or Demodands/Gehreleths, but they do suggest that...
