Does anyone know if Chuck Palahniuk is planning to write a third book in the Damned series?

I just finished Doomed and the ending made it seem like there is a possibility for a third book, but it could also have easily been the end of the series. Personally I think it would make for a good trilogy, and I would love to see more of Babette, Archer, Leonard and Patterson, since we didn't see very much of them in the sequel.
