Batman: Arkham City "Harley Quinn's Revenge" DLC trailer launched

It seems the next DLC pack for Batman: Arkham City will cast Harley Quinn as the main villain. Though the "Harley Quinn's Revenge" title seems a bit spoiler-y to us.

Notice the tagline at the end? "Payback's a bitch." For those of you just joining the story, Arkham City's developer, Rocksteady, was called out last year for allegations of sexism for overusing the word "bitch" in reference to female characters. Could they be resurrecting the controversy to stir the pot?
