Well we can piece a few things together. At San Diego Comic Con, he teased that the Riddler would be returning to Batman in 2013.
He's indicated that the next arc after Death would be his most daring.
And in the Batman #0, it ended telling us that we'd be seeing more early days stories in 2013.
I think we should join those dots. And they make a question mark. The early days of The Riddler, Scott Snyder's most daring Batman story yet?
I could go for that.
