After years of talking about the possibility of changing your PlayStation Network handle, Sony is finally close to making that seemingly basic feature a reality. The company has announced that it will soon launch a PSN Online ID Change beta for "select" users who are part of the PlayStation Preview Program. Your first name swap will be free. After that, it'll cost $10 per change ($5 if you're a PlayStation Plus member) to discourage abuse. The preview for the feature will end in November, but don't worry -- it should reach all PS4 owners by early 2019.
