After all, I chose my PSN ID---like all my gaming IDs---years ago and am perfectly fine with it. The unwashed masses won't have access to the PSN ID Change feature just yet, however. Once it's rolled out to all PS4 users, gamers will be able to change their PSN ID as many times as they'd like. Reverting back to an old ID will resolve most issues caused by the ID change. I certainly can't imagine paying to change my ID and see this mostly as a deterrent rather than a revenue stream for Sony.
