This morning at its E3 2011 Xbox Media Briefing, Microsoft announced that YouTube will be coming to Xbox Live this fall. They didn't go into too much detail about it, but you'll obviously be able to search and view videos from the YouTube service, and we're gonna go out on a limb and guess that you'll also be able to upload gameplay videos taken with Kinect directly to the service as well. Even without that last part though, adding YouTube is just another step Microsoft is taking in their hopes of making the Xbox 360 the ultimate living room hub.
