Wow, it's amazing how some things never change. I'm hearing the same sort of comments here as when Morrison's end-time on Batman and Robin was approaching. "It's his story. DC will discontinue the book once he finishes his story." Yeah, right. The current incarnation of BI was announced as an ongoing title, not a limited series. And Burnham has said on this very forum that it's his understanding that the book will continue with different creators when he and Morrison leave.
That would make a lot of sense.In my mind, Batman Inc is a nice opportunity to cancel the struggling Batwing book and fold David into a "Batmen of All Nations" style book.
