Valve may announce Half-Life 2 Episode 3 later this year.

Marketing director Doug Lombardi says announcement may arrive later this year, though game is still more than a year off.

Although an announcement may be impending, a release date remains farther away on the horizon. "The next time you play as Gordon will be longer than the distance between [Half-Life 2] to [Episode 1], and [Episode 1] to [Episode 2]," cryptically noted Lombardi. Half-Life 2 was released for the PC in November 2004, with Episode 1 following in June 2006 and Episode 2 debuting alongside The Orange Box in October 2007. Doing the math, that would put Episode 3's release date as far off as 2010.
