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.
 * According to Jeff Strain the development time for each campaign is roughly 1 year (source).
 * The third chapter, Nightfall, will be released on October 27th, 2006. Given the 2 chapters a year schedule that would place the 4th chapter release in April of 2007.  One ould predict that since both the original Prophecies Campaign and Factions were released on April 28th that the fourth campaign will be as well.
