Divine Soul sorcerer gets some.
Giant Soul (also UA) gets them as well.
Divine Soul and Shadow Magic Sorcerer get one each.
They didn't get more then that because it was seen as unfair to the other Sorcerer subclasses as the one weakness of Sorcerers is universally few spells known, to make up for their other powers.
I like the Aberrant Mind, it reminds me of the Foulborn, other then the balance issue around the bonus spells.
Love the Lurker of the Deep. Release the Kraken. Also great for Dagan, Istishia (Primordial/God of Water in FR), Archelementals of Water, Marid Princes, some 4e Primordials, Aboleths, Leviathan.
Also it's a safe bet we are getting a Psionics book of some sort, although it might not be a Setting book, neither of these fits Darksun and the Other (Wilder Barbarian, and Astral Monk) two fit Darksun even less.
But this appears to also rule out Rick and Morty.
I think this will be a major splatbook, with the Psion class and various Psionic subclasses.
Also I think we know why the Archivist did not make it into the new Eberron book even though it was more popular then Alchemist, it's the Psionic subclass for Artificer that going in this new book.
If we get traditional none Darksun, Psionic Races in UA, that will confirm it. Like Elan, Maenad, ect...
