In my opinion sony has made a big mistake with this idea! You wont be able to feel the impact from smashing into other vehilcles(which really sucks if they have added damage in GT5) or the vibration of your engine when you upgrade it, no vibration when you peel out or when you race in the rally circuit. It would be sweet if the controllers had both, the motion sensors and vibration technology ( and that does seem like two much to ask for spending $500-$600). I just feel that GT is such a detailed game as far as how the cars feel and ride that this will really hurt the game! Hopefully they come out with new controllers with vibration soon after the PS3 launch!!
