New Arkham City DLC pack lands Dec. 20, takes us to the Batcave

Well, we don't know for sure that the Batcave challenge map included in the next Batman: Arkham City DLC pack isn't the one Adam West and Burt Ward called home, but it seems far more likely that we'll be beating down Gotham's worst in something a little more contemporary.

According to this tweet, the pack arrives December 20 and also includes two previously available maps: Iceberg Lounge and Joker's Carnival. No pricing information has yet been revealed, though we feel safe in assuming that the sum total will cost more than nothing and less than a hundred billion dollars.
