I don't read many current DC Comics titles. The only DC titles I collect are Jonah Hex, Supergirl, the Oracle mini-series and I just recently added Green Arrow and Black Canary, so I have very little knowledge of what's going on in the DC Universe. DC Comics hires hack writers like Grant Morrison and Geoff Johns so who can blame me.
Anyway, I stumbled across this on The Source. Batgirl #1 coming this August. I'm guessing it's Barbara Gordon back as Batgirl since the current Oracle mini-series is titled "The Cure".
