Back in July, Sling announced that one of its first new offerings in almost two years would largely be a software refresh. The out-of-home TV-streaming outfit revealed that, in addition to a new $150 WiFi-equipped M1 option, the familiar-looking SlingTV would replace the pricier Slingbox 500. Well, the time has come, and the new wedge-shaped set-top box that's nearly identical to the 500 on the outside delivers that retooled UI as it goes on sale today. If you'll recall, part of the redesign includes "excitement ratings" from Thuuz that let you know when you should switch over to the big game based on score changes, momentum swings and analysis of the matchup. In addition to the new $300 device, folks who have already splurged for the Slingbox 500 will be privy to a software update that will bring all of the new features to their living rooms -- which includes a remote refresh that's coming to iPhone and Android apps next week.
