A video of an HTC Radar, Kinect and a laptop all working together released. The video below is from the HTC Radar's Hong Kong launch, shows off a Kinect game running on a laptop recieving input also from a player using an HTC Radar, presumably creating the waves in the game.
The game looks pretty close to the real deal.
It is unclear if there is an Xbox powering the Kinect in the video, but it does look like the Kinect is directly attached to the laptop. Either way, we can begin to see how the three different platforms can eventually be connected.
Winrumors said that Xbox 360 games will be linked to Windows Phone devices using QR codes.
