From Blizzcon 2011: WoW Open Q&A
Is the guild name change service going to be in 4.3 or 5.0? Will it fall to the wayside like Dance Studios did?
One of these days we are going to unleash Dance Studios to the world and it will be awesome. But not today. We are releasing the new guild services within two weeks.
You guys going to switch back to paragon and rename?
