In an interview with NowGamer, Rocksteady's Dax Ginn explained that the decision to release Batman: Arkham Knight on PS4, Xbox One and PC and not Wii U, PS3 and Xbox 360, was made in response to the question: "what do we have to do to make the Batmobile work?".
"It was the one thing we hadn’t done," Ginn explained. "Once we decided we were going to commit to the Batmobile, all these other technical decisions were made for us."
"We knew that we had to do it right – the imagination of the experience of driving the Batmobile that people have is that it’s fast, that it’s destructive, it’s kind of a tank in Gotham City, but it’s also highly technical – all of those things can only be done on next-gen," said Ginn.
The site also asked Ginn whether this means that Arkham Knight is a game that just wouldn't have worked on PS3 and Xbox 360.
"Not in the way that people imagine it. It’s the power fantasy of driving this legendary vehicle; if it can only do a top speed of 25 mph that’s not the power fantasy and that’s why we couldn’t have done that previously," Ginn responded.
"We have to make our technology choices specifically with reference to the gameplay objectives that we want, so we choose the platforms that are going to give us that," said Ginn.
