Nintendo's innovation may be catching on. At this week's Consumer Electronics Show in Las Vegas, CNET.com reporter Will Greenwald reports on a PlayStation 2 controller that looks awfully familiar. Greenwald writes that the DualFX Controller is "a two-piece PS2 controller with tethered halves: a gun trigger and an odd laser movement system. The left half of the controller is a fairly average analog stick with a D-pad and shoulder buttons, similar to the left side of a standard PS2 controller. The right half, however, is a gun-like device with a laser pointer. The laser tracks movement in the controller and lets players actively aim in first-person shooters. The laser system proved very inconsistent in hands-on tests, but it is, at the very least, an interesting approach." Look for the DualFX to show up in stores in March for around $60.
