Microsoft announced a new initiative to add live streaming television on Xbox 360 at today's press briefing, and teased a video of the service being controlled through Kinect. Though specific partnerships weren't announced, the company promised more details on that in the coming months. The streaming is said to be coming with the fall update.
We heard rumors that the company was partnering with AT&T for the streaming TV, but no such partnership was confirmed today.
The conference is still underway. Shacknews will update this post as more information is made available.
