Sony stated the name change is not guaranteed to be compatible with all PS4, PlayStation 3, and PlayStation Vita games.
The beta test of the new feature will be available to users who have previously registered as testers for PlayStation 4 beta services.
Testers for the feature will be able to change their online ID in the service during the beta, with the first change available for free, and further changes available for US$9.99 (US$4.99 for PlayStation Plus subscribers).
The beta will conclude in November, with the feature planned to be made widely available by early 2019.
