I say concedes, because when it comes to bowling, tennis – heck any game – you could just move the Wii-mote or Nunchuk a half inch and get the same accuracy – and reaction – as flinging it 3 feet. From the looks of it, they’ve added in an accelerometer. Put that in combination with the motion sensor you’ve stuck on top of your TV and it’ll reflect your action in what Nintendo calls a ‘true 1:1 response’.
Let’s just hope the games of the future take advantage of this.
