Looks like it's still "on the way":
Eurogamer has posted a new interview with Blizzard Entertainment's Paul Sams and Lee Sparks. The conversation covers the topic of paid character customization for the company's popular MMO, World of Warcraft. When added to the game players will be able to pay a small fee to change specific aspects of their characters not currently available for modification.
"When you create your character, often times you wish you'd done things differently. You wish you were on a different realm, you wish you'd had a different name or you wish you'd chosen a different look and feel to your character. "This is a way for [players] to be able to do that, but it's something that's taking a lot of time and energy for us to be able to put in place. We also think that it's important to have some consistency in the game, we don't want people changing their look and feel every day," Sams said.
Wrath of the Lich King allows players to change characters' hairstyles, jewellery and other superficial details in barbershops for a small in-game currency charge. It seems that the new feature will allow more fundamental changes - facial features, skin colour, perhaps even gender or race - although Sams and Sparks didn't discuss specific options. We asked whether the feature was more about making changes to decisions made in the past than adding additional options, and associate producer Lee Sparks said that it was.
"Yeah, and I think the reason for the monetary expense is more of a barrier so that people don't do it every day," Sparks said. "We want to give you the ability to do this, but we don't want you to do it all the time time. The same thing goes for paid character transfer, we don't want people bouncing back and forth."
