I think both SIXAXIS and DS3 controllers are really interesting in designing and working. sony change them for what??maybe if sony wants to use new options in these controllers should change it .otherwise no change is necessary.my brother has a XB360 Elite and i also played with it's controllers and i think PS3 controllers are more comfortable than XB360s.the ones who raised up with PS series like me,wanna these controllers remain in their shape.
