This year we can finally sit back on the sofa and watch the Xbox media briefing, known as Xbox: Entertainment Evolved, at this years E3 2012 direct from our Xbox console. The announcement came earlier from Major Nelson. As of yet no more information is given, but it will likely be held on the Live Event App that was used a month ago to watch the Rock Awards Show Live. See the Spike TV promotional video on the blog.
It will be airing on June 4th at 12:30PM ET/ 9:30AM PT.
