Development of Kinect for Xbox 360 exclusive Ryse from Crytek is moving along very nicely, despite not being publicly shown, Crytek GM of games Nick Button-Brown has told CVG.

"It's doing really well and we're really, really happy with where it's going," said Button-Brown.

"It's our annual thing; we show a trailer for Ryse at E3," he joked. "It's going really, really well. The team actually delivered a milestone yesterday, which was quite nice. It's kind of good to see that."

So when are we likely to see more on the game? Button-Brown wasn't saying: "We're really happy with it and at some stage will be showing and giving more information about it. Unfortunately we're kind of constrained by our publisher."
