What Arcane traditions, Domains, Pacts, Bloodlines, Schemes, and other in class specializations would you like to see.
To get the ball rolling I'd like to see Beguiler and spellsinger as an Arcane Traditions, Relic Hunter and Shadow Thief of Amn scheme, Underdark Bloodline for sorcerors, Passion Domain, and Fey, Star, Gloom, Dark, Infernal pacts as well as Slaadi pacts, and demigod or angel/immortal pacts (this last pact would count as divine instead of shadow or arcane magic).
Bloodlines and Pacts haven't been confirmed, but they're a safe bet.
