[quote]Since the Bungie Name feature went live, players have been asking when they can change their name. We are investigating a way for players to change their Bungie Name in a future update and are currently targeting a date close to The Witch Queen’s launch date. Upon an investigation into a player’s real name being used for their Bungie Name, we have determined that this issue occurs when a player sets up a Steam account with an email containing their name, doesn’t change their Steam account name upon activation so it takes on the email address name, and then doesn’t add in a Steam display name. If Steam doesn’t have a display name, our Bungie Name feature will take Steam’s account name to use as a Bungie Name instead. [/quote]https://www.bungie.net/en/Explore/Detail/News/50975

There is no set date for it yet.
