Well, I am pleased to announce that this will not be the case. According to official releases: "When asked on a recent episode of The View about his plans to retire, Stephen said that he has enough projects to keep him busy for the next 2 years and that he'll make a decision about retiring then. Don't worry, folks, finishing The Dark Tower books is first on the "to do list" during this next 2 years."
For more info on the direction of the Dark Tower story, read the interview that Steve did with, well, himself.
I am Chaos's adrenaline shot.
