DC's Geoff Johns is also expected to have a role in the Supergirl project, which is in the early stages of development and expected to be taken out to networks soon.  Johns exec produces Arrow and The Flash.

Sources tell THR that the project will not be called Supergirl. 

The Supergirl entry comes as comic book adaptations are poised to have a major presence on the upcoming fall schedule.  In addition to Berlanti's CW series Arrow, he has spinoff The Flash at the network.  Both hail from WBTV and DC Entertainment, which also are behind Fox's Batman/Jim Gordon prequel Gotham, NBC's Hellblazer take Constantine and The CW's iZombie adaptation.
