Hasn't launched a creator owned series outside Vertigo...Delano has done a couple of minis at Avatar, Milligan did The Programme at Wildstorm...Carey could be a possibility. He's been pretty quiet since he left X-Men. Just The Unwritten on his slate at the moment, and the way Vertigo is headed I wouldn't be surprised to see him launching something elsewhere for when the axe inevitably falls.
[EDIT] and I got Ninja'd by Niels, who seems to have it nailed. Well, this should be something to look forward to, then
