Since players got their hands on the full retail copy of Batman: Arkham Asylum last week, a ‘news ticker’ scrolled during the start screen promising some downloadable content. No one knew exactly what the developers, Rocksteady Games, had planned or when we would see this new content.

Joystiq noticed today that the same ticker actually changed and is now reading that the DLC is coming out in “9 days,” which falls on September 17th. Not only is it going to be released in a few days, apparently the text is suggesting the content will also be free, which should be welcoming to gamers.

Obviously everyone is wanting to know what we should expect when the content is released, but right now Rocksteady is being mum on the situation. I hoping by the end of the day, we’ll get more details.
