If you haven't heard, Sony has gone into the Wii realm with the motion sensing controllers. They name it.....Playstation Move.. Basically, it is a better version of the Wii-mote plus and Nunchuk....yea.....Anyway. I watched a live feed from the GDC out in California and there was a presentation and all of that for it. They demoed games such as Socom 4 and Motion Fighter with the remote....Maybe you are interested in it....or not. Anyway, there is a link with the info for it.
