There was yet another new server added today, a new PvP Server! For those interested here is the information from Blizzard:

We are pleased to announce a new PvP realm, Smolderthorn! This realm is now live and available to players. Since the introduction of the Honor System, intense battles have been raging across the lands, and dedicated adventurers are trying to reach the highest ranks. Will you be first player to reach Grand Marshal? Will Thrall soon be calling you Warlord? Create a character on this new realm and let the race begin!
