Moreover, Sling TV also announced the addition of ESPN3 to the "Best of Live TV" bundle, something that's going to please hardcore sports fans -- though it won't be coming until "later this quarter." Similarly, Sling TV's revamped look won't be rolling out until sometime in Q1 2016, but at least now you know it's on the way. That said, it's worth noting this is meant for devices including the Xbox One and Roku, so expect it to appear a bit different on mobile devices.
