Why only Pc?

I think the Playstation Move would be a great controller for Penumbra-like games. Even better than mouse at times (far better than the Wii). Move is tracked in 3D and is as precise as mouse, so you could reach right in the game, grab the door knob and open it like a real door, or swing your weapon like you would do for real for that matter. It would be a dream if games like this showed up on PSN or retail for the system.

I still don't buy the hype for that or Kinect. Wii had the same hype before it came out and it has extremely gimped and unresponsive motion control.
