Preacher is a book that somehow allows me time by its settling on it's characters, that sort of modern gothic western feel. You're not likely to see the boat veering too far from that.
It's nice to be in a situation where the two books that I write for a sort of regular monthly income are also works that I enjoy immensely, rather than them being some kind of bread and butter, do it because you have to do it.
Most regular superhero books are designed to go on forever; of course, very few of them do, but the point is they are trying to throw mud against the wall and hope it will stick, and most of it slides off.
I'm sure you're aware, with the time it takes to put these books together, everything can suddenly start coming out at once even though I wrote anything between one and five years ago.
