Hoping for 2-3 PHB-subclasses and 1-2 popular/thematically appropriate non-PHB subclasses for each class. Balanced approach between development resource management and satisfying player expectations and agency.
Psionic subclasses would make a lot of sense given the setting:
Psi Warrior for Fighters
Psionic Blade for Rogues
Aberrant Mind for Sorcerers
Other favorites would be:
College of Eloquence for Bards
Path of the Beast for Barbarians
Gloom Stalker for Ranger
Scout for Rogues
Divine Soul for Sorcerers
Hexblade for Warlocks
Bladesinging for Wizards
