Burnham gave us an update on his recent projects, which were mostly focused on Batman. He also came just short of giving us a scoop on some mysterious future project. If it is indeed "bigger and better," we will certainly want to know about it.
Burnham is a good guy and if possible, I am sure he will give us more information and maybe even a scoop at some future convention. Until then, I suggest following Chris Burnham on twitter to keep up with his work.
