I'm surprised with the release date is not delayed to next year. Anyway it's a bit misunderstood by DC Comic staff at Wondercon. DC editors (Mike Cotton, Jim Chadwick and Shelly Bond) said that Batman Arkham Knight is going to fall this year but Injustice would be delayed to next year.
I'm extremely sorry for the previous article here. Just keep stay tune with us to get more updates for Batman Arkham Knight.
