PS3 owners will get an exclusive costume after purchasing the 2D or 3D versions of the feature film's Blu Ray release. The Batman Sinestro Corp costume will see the caped crusader don yellow in the get-up of the villainous foes of the Green Lantern universe. The Blu-ray hits shelves on October 14th, four days before the North American launch of Arkham City, and a whole week ahead of the European launch. Sources say this gives you ample time to admire Ryan Reynolds in CG before entering Arkham City.
