Yeah, figured that'd be the case, it bothered me a bit at first but then ended up getting used to it and even liking it - felt more real than just having any random author on it. I think King has said he'd like to go back to it and remove himself from the story, kinda like how he revised the first books some years ago.
Btw, anybody know if there will be hardcover reissues of the series? I'd really like to get my hands on one, there are a few rare spanish ones but would definitely prefer them in their original language.
