According to the Guild Wars 2 Twitter, the final class available to Guild Wars 2 players is the Mesmer. NCSoft had embargoed the reveal for this Wednesday, but a video made its way online anyway. Before its removal, the jubilant Mesmer fanbase got word of it, so there’s no stuffing the cat back in the bag. Expect a full reveal with trailer and details laster in the week. The MMORPG is expected to launch in 2012.
