Vibration hasn't been this big of a deal since 'Sex in the City.' As of right now, Sony's PS3 will not include rumbling or vibrating technology in its next-generation controller. An outstanding legal issue with Immersion (to the tune of roughly $91M) coupled with Sony's claim that the rumbling technology is incompatible with the motion sensing technology in the PS3 controller has current iterations of Sony's controller sitting idle.
How will rumbling controllers play into the next-generation console war? Will gamers notice if the controller doesn't vibrate taking a corner in Gran Turismo, will they care? Immersion President and CEO Vic Viegas certainly thinks so: "If you can see a single blade of grass in Madden and hear the hot dog vendor in the stands, but you don't feel the tackle? That's not going to sit well with gamers."
