To be clear - BattleTag does not display your real name to anyone. It's an anonymous nickname system. The entire point of BattleTag is to be a unified, anonymous nickname you'll use across all Blizzard games.
The Real ID system, of course, does display your real first and last name. But you have to choose to be mutual Real ID friends with someone, and only then will you both see each other's real first and last names.
Real ID and BattleTag are separate systems, and they don't intersect. The intent with BattleTag is specifically to offer all the great features we've been able to offer with Real ID (cross game chat, etc.) but with an anonymous nickname.
The game displaying your own real first and last name to you, I understand, is a concern for some, and we appreciate that feedback. It is not, however, displayed to anyone else, or part of the BattleTag system. The only way someone else can see your real name is if you've both mutually agreed to become Real ID friends.
The current implementation of BattleTags in the Diablo III beta is of course a first go, and we've already read a lot of feedback and are aware of a number of issues. Keep it coming, though.
