while i would love for it to be sinestro since he is one of my all time favorite comic book villains, i highly doubt it due to the green lantern animated series airing right now, dc wont want the same characters having the focus in 2 different shows.

it happened back during the justice league tv series, they didnt use any batman villains for that show because there was a seperate batman tv series airing at the same time, and that show wasnt allowed to use robin until teen titans ended
