Green Lantern and Green Lama

DC has been promoting its upcoming Rebirth event as a celebration of the history that made the DCU great.  I am hoping that means the return of the classic JSA characters with their World War Two era adventures intact.  The legacy aspect of these heroes was noticeably lacking in the New 52 relaunch and having the original Alan Scott and the rest come back would go a long way towards winning back some lapsed fans.
