We've known for a while now that Kinect's Australian launch date would be sometime in November. It looks like that date is now November 18.
IGN AU is reporting that Microsoft confirmed the date to them at a Kinect preview event earlier today.
Microsoft has not yet officially announced the launch date, so we're following up with them to confirm the IGN report.
Kinect enables controller-free motion gaming on the Xbox 360 along with voice and facial recognition technology. The accessory retails for $199 bundled with Kinect Adventures.
