No really this is about Batman's early years. The origin is going to be done thru flashbacks like in Burton's Batman but this is about a novice Batman in a modernized world with reinvented characters that range from simply modernizations to re-inventions.
I think alot of people seemt o think these OGNs are just retells of the origin, but there really about the first years just like "The man who laughs", "the long halloween" and so forth are.
