Of course, there's still one question that everyone is waiting to find out: Now that the official introduction has been added, how long will it be before we see Mists hit live servers? It's going to take a release date before we know that one for certain. However, the fact that the 5.0.4 PTR is now live seems to suggest sooner, rather than later.
It's open warfare between Alliance and Horde in Mists of Pandaria, World of Warcraft's next expansion. Jump into five new levels with new talents and class mechanics, try the new monk class, and create a pandaren character to ally with either Horde or Alliance. Look for expansion basics in our Mists FAQ, or dig into our spring press event coverage for more details!
