Blizzard has announced two new WoW realms.

We are pleased to announce the opening of two new realms: Tanaris which is a PvE realm and The Forgotten Coast which is a new PvP realm. These new realms will provide a great place for new and old players alike to begin fresh adventures within the world of Azeroth. Enjoy!
These realms and any future new realms will be made available for the Paid Character Transfer service 6 months past their launch.
