There is a very interesting article with Michael Emerson of LOST about the upcoming season 4. Not a lot of new information, but it's an interesting read and he drops hints like: "I think Ben is dead right about that. I think we can trust Ben on that one; that the people on the boat mean them no good." and "But these new characters are really intriguing and some of them are quite dangerous. It's going to be interesting."
