"(on upcoming issues): Action Comics #1000 will be starting the Superman run with a tease. Superman #400 is one of my favorite comics of all time, a celebration of comics in general. And so, to be part of the thousandth version of that is so exciting. We’re using it as the jumping off point for Man of Steel #1, a big event with each issue drawn by one of the biggest artits at DC. It will end with a new status quo, a new situation for Superman in the DC universe. And then it will be followed by Superman #1 and Action Comics #1001."
