Not that Batman has ever gone wanting for action figure exposure, but the Caped Crusader's getting a new line based on last year's Batman: Arkham Asylum game. It'll be revealed in next month's issue of Toyfare magazine.
The line is from DC Direct. No other details are yet known, but if I had to guess, aside from the absolute necessity of Batman and Joker I don't see how this line goes forward without Harley Quinn and Bane - as they appear in the game of course.
Toyfare will have all the details in its June 2010 issue.
