The link I have provided leads to MAJOR SPOILERS for the upcoming Batman #32, coming out this week. So if you don't want to be spoiled, DON'T CLICK ON IT! You have been warned
Without spoiling anything in my post, all I will say is, "It's about time we got an answer, took DC long enough!"
Regardless of what her answer is, I cannot get excited given that in the next 5 to 10 years DC will once again have another Crisis style event and reboot everything and erase what they don't like.
