Microsoft and Sony are "testing the water" for the next generation of consoles with Kinect and PlayStation Move, 2K chief Christoph Hartmann believes.
"I don't think they are avoiding doing another machine but testing the water," Hartmann told MCV.
"Rather than coming out and saying 'this is our console now,' I think they are playing around and seeing what they can do," he explained. "These guys know how to manufacture the chips or push the memory, the kind of thing you usually get with each new console generation. But now everyone is looking for innovation and at online components, so they are experimenting."
