Richard Garriott Actively Developing Another RPG

According to his latest Twitter entry, Ultima creator and Portalarium founder Richard Garriott has proclaimed that his company has "deeper offerings in the works" specifically for "RPG gamers". As you probably guessed from my news title, I don't see any other way to take that other than to assume he's actively developing an RPG for one platform or another:
RPG gamers fear not! Portalarium has deeper offerings in the works! Small games help us build tools and audience. Lord British games coming!
I think he should call it Umtila.
