In a recent Podcast with Kyle Higgins, he hints at the future of Nightwing!
"Issues 17-18 are the fallout of the Joker story, and after that I don't think I can say; It's Exciting! I don't know when they will announce it, but when they announce it, it will be surprising! When you see why it happens you'll not only understand it, but you'll cheer for it to happen."
What could it be?
Maybe Bruce asks Dick to raise Damian?
Maybe he takes the mantle of Red Robin if Tim dies in Death of the Family?
Anyone have any ideas?
