Speaking to Kotaku, a Microsoft representative explained that at the time of the launch of the Xbox One console, you will not be able to use our real names on Xbox Live but only our Gamertags.

"While real identities continue to be part of our future plans on Xbox One, at launch, customers will continue to find your friends using their gamertag. Our teams are working hard to provide a quality experience for the Xbox One. This means giving priority to some features and, sometimes, postponing others for future updates " , said the representative.

Wait confident further clarifications from Microsoft although most likely, different users will remain faithful to your gamertag without disclosing their real identity on Xbox Live as already happened on the Xbox 360.
