How do you improve on the foundation established by the first two games in Rocksteady's Arkham series while still retaining the things that players have come to associate with those games?

The demo may have shed light on some of Arkham Knight's gameplay surprises, but it also raised one tremendous question: who is the Arkham Knight? As the demo came to a close, Batman was attacked by a figure whose identity was unclear, but who seemed to be a formidable warrior capable of going toe-to-toe with the caped crusader. This, Ginn said, was the Arkham Knight, a new character created by Rocksteady in collaboration with DC, and a character of tremendous importance in the game's story. My suspicion is that, like the character of Red Hood in the Batman comics, the Arkham Knight will end up being a character we already know; perhaps it will be the Joker, making one final appearance, revealing that his apparent demise in Arkham City was one big, elaborate joke. But maybe I'm wrong. Maybe the joke's on me.
