Brian Michael Bendis, who over the last few years has developed into one of Marvel's most bankable creators, has extended his exclusive relationship with the company for a period of unspecified duration.  He's currently writing the top-selling House of M (see 'House of M Boffo at 233k'), and is also working on Ultimate Spider-Man, Daredevil, New Avengers, Secret War, and Powers.  Marvel EIC Joe Quesada said of Bendis, 'He's...singlehandledly created a fanbase that's truly overwhelming.'
