We know that a solo Batman movie starring and likely directed by Ben Affleck is on the way some time in the future, and co-writer Geoff Johns recently commented on one aspect of the film's plot, that it will focus heavily on the demise of Robin, as hinted at in the trailers for Batman v Superman. Johns said, "Well be exploring , no one says specifically the name of which Robin that is." So, while the identity of Robin still remains under wraps (Jason Todd? Dick Grayson? Tim Drake?), we know that this won't be a disposable plot point for BvS, and could very well feed into a Joker-Batman showdown in the Caped Crusader's next solo film.
