If Batman: Arkham City news is what you were looking to get out of San Diego Comic-Con, look no further. First up, GameSpot has the new trailer for the Penguin. Another villain is shown near the end, and it's not someone I would have necessarily thought would make an appearance in this game.
In related news, voice actor Kevin Conroy spoke to Comic Booked about the future of Arkham City, saying "it's going to be an ongoing game. You're going to be able to download future episodes of it, so it's going to be going on for quite a while. I've been recording it for a while. So that will continue."
Downloadable content for a popular, multiplatform game? You don't say.
