Guild Wars 2's Flame and Frost content extravaganza has been dated. That date is February 26th, and you can expect to see a new PvP map called Spirit Watch as well as new guild missions and merits.
There's also a new type of competitive PvP in the wings, and it involves two teams of "equal average rating" duking it out in quick matches with ratings and bragging rights on the line. More details are yours on the official GW2 website.
