Arenanet started writing the original Guild Wars with 5 people, out of one of their founder's apartment. Today 270 Arenanet employees plus 100's of NC Soft (the publisher) employees in Europe and Korea are working on Guild Wars 2. (The original once again has a small group, 6 people, keeping it updated.)
Arenanet announced Guild Wars 2 in early 2007, as an explanation for why Guild Wars: Utopia a planned 4th campaign, had been canceled. They did not seriously start working on Guild Wars 2 until late 2007 however as they were still working on the Guild Wars expansion Eye of the North, which is a link to Guild Wars 2.
