Those sneaky-sneaks over at DC Collectibles released a couple of photos an hour ago on their Facebook page of some previously unannounced Arkman City 2-packs that fit in with their long running 7″ action figure line:

Batman Arkham City Mr. Hammer and Harley Quinn Action Figure 2-pack

Batman Arkham City Sickle and Penguin Action Figure 2-pack

No information has been released yet about when these will be available or how much they will run.
