The most exciting reveal for me was the creative team on The Stand. It's one of the only Stephen King books I like, in fact it's probably my favourite of his. I've been clamouring for either a comic, a movie or a (decent) TV series for years. Roberto Aguire Sacasa (?) is a decent and underrated writer, and Mike Perkins should do a great job on art. Those images of Randall Flagg are pretty damn good.
Can't wait for this.
Update: according to interviews, it's going to be about 30 issues long, separated roughly into 6 five issue mini-series. The creative team are in for the long haul.
