Only dates that are officially announced by ArenaNet will be posted here!

However, for personal estimation of the release date, the following facts may be provide some starting points:
 * ArenaNet have stated that they plan to release two campaigns per year, released on staggered six month cycles. Factions (campaign 2) was released April 28, 2006 and Nightfall (campaign 3) was released on October 27th, 2006.
 * According to Jeff Strain the development time for each campaign is roughly 1 year and that ArenaNet now creates two campaigns at a time on overlapping schedules.
 * During E3 2006 ArenaNet confirmed that developement on Campaign 4 was well underway.
 * ArenaNet sent out the first wave of alpha test invitation emails on January 9th . On December 12th Gaile Gray stated that testing (from the context, implicitly out of house testing) for campaign 4 has not started.
 * An NCSoft press release from February 7th, 2007 states that "... the company anticipates the launching of Tabula Rasa and a new major update to the Guild Wars franchise in the latter half of 2007", which may refer to the next campaign.
