I'm stoked about the JMS book. He did a great job with Hyperion from Supreme Power so I know he can bring it with Superman. Not so sure about Johns on Batman. Johns is definitely talented and I love what he's done with Hal Jordan for the most part, but in some of those GL books he makes Batman out to be prick and I wonder if he can really give the character a fair shake. He seemed more interested in playing with the villains than doing something original and unique with Batman, whereas JMS seemed to be more focused on Superman/Clark Kent.
