SDCC 2013: Batgirl to appear in Batman: Arkham Origins?

The Batman: Arkham Origins panel has just ended at San Diego Comic-Con 2013 and a lot of interesting information was released during it. However, one tease really stood out: When asked about the existence of Robin in the game, the panel replied:

There's no Robin at this point in the timeline. This is year 2 of his career. As for Batgirl, you're gonna have to see the game. #ArkhamSDCC

Now, that's a pretty strong hint isn't it? I'd certainly love to see Batgirl in Arkham Origins, but I'm still hoping for at least a few little hints or references to Robin.

As well as this, another interesting piece of information from the panel is the reveal that DC Comics assassin, Copperhead will be appearing in the game. Copperhead has recently appeared in mainstream comics as a member of the Secret Society in Justice League of America, except the version in the game will be female.
