BioShock publisher 2K reckons the next Xbox and the PlayStation 4 will come with motion sensing peripherals PlayStation Move and Kinect as standard.
Both Move and Kinect are "experiments," 2K boss Christoph Hartmann told MCV.
"I don't think they are avoiding doing another machine but testing the water," he said.
"Rather than coming out and saying 'this is our console now,' I think they are playing around and seeing what they can do.
"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.
"It's not been a case of just jumping on the Wii wagon – it's been a case of learning about what Wii did and trying to take it somewhere.
"When Microsoft made the Xbox, I assume there were always plans for Xbox 360. It was just the first Xbox was the machine to get it there. Microsoft was new to the party, so they used Xbox 1 to test the water. It's the same principle."
At E3 last month Sony announced 8.8 million Move controllers had been sold worldwide.
Kinect, meanwhile, has shifted 10 million units since its November 2010 launch, and is the fastest-selling consumer electronics device in history.
