Rocksteady has not made up their minds for a demo yet, but if they do decide to release one, then it may come out either on September 31 or October 1 ( The time the demo for Arkham Asylum came out), or October 4 ( Two weeks before launch), or October 11 (One week before launch). If its not out before any of these dates then Rocksteady most probably didnt want to make a demo, and you would just have to wait until it releases October 18. They will most probably release one because the people at Rocksteady know that Batman Arkham City is a highly anticipated game, but if you ask me..i wouldnt very much mind waiting another 24 days for the full game because it makes the whole experience much more worth-while.When will the Batman Arkham City Demo be ready ?
