For those who haven't heard yet, they plan to finally reveal the identity of The Joker. Poor move man, poor move. If they reveal it as someone readers know and is shocking for Bruce to discover(as they implied) than that kind of shits on Batman's detective skills and if it's a new character than what's the point? Plus how will this play with Snyder's latest joker reveal about him being around for longer than Bruce? The best thing they can do is leave it ambiguous.
