Image Numero Tres of the NEW Batgirl on DC's Blog:
Honestly, who was expecting Cass to still be under the cowl? Don't get me wrong.. I crossed my fingers and wished it would be so...but alas it wasn't meant to be. Probably because she doesn't have an impressive enough fan-base. Excuse me, what I mean to say is not that her fan-base isn't large enough but that Cass Cain doesn't have an impressive enough fan-base to be recognized or even slightly visible to the DC bigwigs.
I told my comic shop guy I knew
Cass wouldn't be flying as the Batgirl come August, but he strongly disagreed with me. He also continued in his explanation promising that Didio himself said he would never put Barbara back under the cowl. I wasn't privy to this knowledge, if it is fact
...which I am not wholly convinced on or otherwise DC forums wouldn't be filled with the nervous chatter of Barb's cape resurrection.
My money is on Stephanie Brown. Though it is difficult to put my GoStephanie! fangirl bias aside, I do honestly think Steph would be rad as Batgirl. Not only would she be the first canon female Robin, but to my knowledge, the first person to have ever worked as both
Batgirl & Robin. If thats not fun I don't know what is...
