They've stated the number of new Subclasses, and it happens to be the same number of tested UA Subclasses minus two. So it looks like everything aside from the Onomancer and Psion made it in, plus the Magic reprints and the Bladesinger.
Wild magic barbarian i can take or leave, but the genie warlock i do really like. I wish they'd gone with a more wholehearted way of letting Eldritch Blast do elemental damage though (like they did with the undead pact and necrotic damage in UA recently) - + proficiency damage once per round is pretty feeble - but at least they made a gesture. Dependency on Eldritch Blast and its associated invocations really are a millstone around the neck of the entire Warlock class at this point. And it would have nice to see Planar Ally as a genie pact spell, that'd be really thematic i think.
