G4 caught up with Richard Garriott at this year's DICE Summit for a quick three-minute interview about his new Portalarium venture. During the Q&A, Garriott even specifically states that he'll be developing a "hardcore" Lord British title for the social gaming service (right after talking about Ultima), which leads me to believe that it will be some sort of role-playing game.
I suppose if anything will get me into social gaming, it's a Richard Garriott RPG.
