The Verge report that a number of the highly touted new Xbox One features Microsoft have revealed will be exclusively available to paying Xbox Live Gold subscribers. These features includes the Game DVR that allows you to record and share your gaming achievements, Skype, the OneGuide TV programming guide and SmartMatch.
It should come as no surprise that Microsoft are making more features exclusive to paying subscribers - afterall we need to pay for Xbox Live to watch Netflix (that we pay for!) on our Xbox 360's.
