Pre order this from Play.com - Worth doing to save £20 and chances are it will be out of stock everywhere as soon as it is released (going off what happens with the rest of the Wii stuff!)
Wii jOG is the innovative motion-sensing controller that brings a whole new dimension to your living room gaming experience. With jOG your character only moves when you do. Plug jOG into your existing console and wow! jOG measures the steps you take and translates them to movement on screen! Now, when you move in the real-world, you really move in the game!
I hope ive done this right as its my 1st one!!
