According to Bleeding Cool, Greg Capullo might be jumping ship and heading to DC on Superman or Batman - or with Marvel on Wolverine. The artist is currently at Image Comics with Haunt.
Personally, I would like to see Capullo go with Superman, taking the title in a different direction away from the crappy as heck "grounded" arc - and make it something more along the lines of director Zack Snyder's vision that Supes should "kick ass."
BC also states the Wolverine option is attached to Brian Michael Bendis and that the superstar artist is deciding to leave for the Big Two in order to get some recognition.
I've always been a fan of Capullo - since his Quasar days! Looking forward to whichever book he chooses.
