Finally!

From Bornakk:

Providing a smooth and enjoyable experience for all players is always a priority for us, and we are continually re-evaluating our policies and programs to do so. As the state of the game has matured substantially since the inception of Paid Character Transfers, we will now be allowing PvE-to-PvP transfers on a full-time basis to provide players with more mobility and freedom to easily play with their friends.

Oh man. This is going to prove for some hard decisions. I still have some friends on my native server I'd love to play with but they're both Horde and Alliance. Argh!
