Although Microsoft plans on letting Xbox One owners eventually use their real names instead of their Xbox Live Gamertags, that feature has been delayed beyond launch. PS4, however, will launch with the option of using a real name ID.
Sony confirmed to Kotaku that the real-name option is exactly that: an option. "This isn't an all-or-nothing, named-or-anonymous proposition," the site says, pointing out that you'll still be able to play with your PlayStation Network ID if you don't want people to know who you really are.
Thats the first thing I could dig up hehe
^^^^ this
Yeah I'd understand outrage if it was mandatory. This lets people do so if they want, and others keep their made up name...
