MLB.TV isn't the only app premiering on Xbox 360 today: HBO GO and Comcast Xfinity TV are now live and ready for your viewing pleasure. Both apps are available at no cost for current HBO GO and/or Xfinity TV subscribers, and they are both Kinect compatible.

From here, this looks like perfect timing, at least on HBO's part -- The second season of Game of Thrones premieres on Sunday, and we believe there's no better place to watch a smattering of gory, smutty violence than through the device you use to play gory, smutty games.
