Gamespot has the word that the first of the Half-Life 2 episodes has gone gold. They also have details on the upcoming Episodes 2 and 3. Episode 1 is to be released on the 1st of June. From the article: "In addition to two new multiplayer modes and the Lost Coast tech demo, Episode One will sport a preview of its sequel, Half-Life 2: Episode Two. The expansion, the existence of which was revealed in February, will add another four- to six-hour mini-campaign to the Half-Life 2 saga when it is released later this year. Previously, the game had no official release window or date. Today's gold announcement also was the first official confirmation that a third Half-Life 2 episodic update is in development. Like Episode Two, Valve divulged little in the way of information about Episode Three, saying only that it was the last 'in a trilogy ... that will conclude by Christmas of 2007.'"
