Colten Haynes recently turned 26. A few days ago he mention they were doing a special photoshoot. Perhaps we will see some official Arrow Season 3 posters at Comic Con in the coming weeks.
“In the aftermath of this victory, Season 3 opens with Arrow now a hero to the citizens of Starling. Crime is down, people feel safer, and Captain Lance even calls off the Anti-Vigilante Task Force. Basking in his success, Oliver believes he can finally have a private life and asks Felicity out on a date. But the second Oliver takes his eye off the ball, a deadly villain reappears in Starling, forcing Oliver to realize that he can never be Oliver Queen — not as long as the city needs The Arrow.”
