No, I have heard absolutely nothing. I just figured that one was planned because it was being set up in the last chapter with a new mysterious twist, even though, without it, the novel could otherwise be the ending of the saga in every important way.Sadly, from everything I've heard Promises Broken will most likely be the last The 4400 novel. Unless you've heard differently in the last couple months?I wonder how they'll follow this up in the sequel, which is being set up in the last chapter ... I guess he's meant to reappear in the next novel...
