DC why?

Ummm.....what? It's not going to be one of the big three. Batman is their cash cow, Supes is their history and Wonder-woman is too obvious. I'd say it's going to be Robin or Jimmy Olsen. They are close enough to matter, and won't mess with directly with the big three.. But why? They have had a number of gay heroes and villains. Hell, they had a cyborg and gorilla in a relationship.
