Recently it's been rumored that Portal 2 will offer support for PlayStation Move, the motion controller released for the PlayStation 3 last fall. The source of the rumor: a misquoted Valve representative speaking about the game. To clarify the rumor, Valve passed along this brief and very direct statement today.
There's a story making the rounds regarding Portal 2 support for PS3 Move.
Unfortunately this quote was "lost in translation" -- Portal 2 does not include support for Sony's motion controller.
So there you have it folks. While we'd love to see either Kinect or Move support in Portal, it won't be happening this time around.
