Unreal Engine 4 is up and running on next-gen systems, according to Epic vice president Mark Rein.
Speaking at the DICE summit (via LoudMouthedGamers), the executive said the new engine is now running on "systems we can't name yet".
Rein also told G4TV that Unreal Engine 4 will be revealed later this year.
"People are going to be shocked later this year when they see Unreal Engine 4 and how much more profound an effect it will have," he said.
According to rumours in the latest issue of Xbox World magazine, Microsoft's next Xbox is set to include a Wii U-like touchscreen controller.
The mag claims Microsoft is experimenting with a tablet-like controller with a shape closer to Sony's PS Vita than Wii U's "bulky unit".
It goes on to describe the Xbox 720 pad as "an HD screen surrounded by the traditional 360 buttons and sticks."
