According to IGN, the October 14th Blu-Ray release of Green Lantern will apparently include an access code for a Sinestro Corps Batman Skin for Batman: Arkham City.
Though, content-wise, it would make more sense to include Green Lantern Batman, it's still pretty genius marketing and a nice way to get/trick hardcore gamers into buying a film they might have otherwise blown off.
