New Dark Tower novel next year?

Wow this could be a neat hat trick for Stephen King! According to Cory Doctorow writing for Boing Boing:

• Stephen King has written another installment in the Dark Tower books

Whooooooooo hoooooooooo! Well if you have followed the series like I have then you know the mind bending twist at the end. You know who Roland and The Man In Black are and their "connection" (which lends the question...how long has this been going on?!) Anyway, according to Doctorow:

• The new book, The Wind Through the Keyhole, will fill in some of the action between the fourth and fifth books

ehhhhhhhhhhhhhhh (flinch flinch....one eye starts to twitch uncontrollably...) Well uhh.. Mr. King has the urge to back fill the holes in his narrative and has some pretty clear thoughts on the subject. Instead of just copying them here, I will post the link where you can read it for yourself on Cory Doctorow's blog here
