Blizzard says "someday" and forumites get whiny.

Changing character appearances has been a hot topic over in the WoW forums of late with Blizzard CM's stating that it could be coming in a future patch.

The requests of players were heard by the GMs and they sent Blizzard Poster/Forum Moderator Drysc to announce that this option could possibly be implemented in a future patch. One thing you should notice in the statement given though, is the lack of a time frame regarding the changes.

There's a good overview of the proceedings at QJ.net.
