Batman and Detective Comics #0 show case Bruce's past, Batman Incoprorated #0 show how Bruce recruited all his "lieutenants" for Batman, Inc , Batman and Robin #0 deal with Damian and Talia. Batgirl #0 is supposed to reveal Barbara's New 52 origin and first adventure as Batgirl. I think originally it was supposed to reveal how she is walking now, but that might've changed.
Early reviews of "Batman #0" are that it is outstanding. No surprise here. Pulls tomorrow will be the following:
-Batman and Robin #0
-He-Man and the Masters of the Universe #2
