Sometimes you just want to call people by their real name, and not xxHaloKillerz420xx. Microsoft plans on letting Xbox One use their real names on Xbox Live, however that feature won't be available at launch.
"While real identities continue to be part of our plans for the experience on Xbox One, at launch, customers will continue to search for friends using their Gamertags," a Microsoft rep told Kotaku. "Our teams are working hard to deliver a quality experience for Xbox One. This means prioritizing some features and sometimes postponing others for a later update."
The delay is somewhat notable, given that Sony plans to implement similar real name integration into its user interface. However, other new Dashboard features, like the ability to store 1,000 friends and the optimized friends app remain in line for the Xbox One's launch.
