Once I played the Wii version last yerar I have no desire to use a joystick for a golf game. It's like once you buy a racing wheel it's hard to go back to a joystick for racing games. Looks like the joystick is going the way of the dinosaur by Xmas once the Move and Natal are out.
My advice is to hold off for now buying it or either buy this on the Wii for now if you have one and then trade it in for the PS3\Xbox version when thier motion controllers come out later this year for the better graphics and career mode. You have a level of freedom when you don't care about the joystick and how sensitive it is because once you use a motion controller it's impossible to enjoy the game playing with your thumbs.
