Episode 3: Revenge of the... Combine?

In a recent talk with Gamespot, Valve marketing director Doug Lombardi unveiled an interesting tidbit- The expansion pack for the newest entry into the Half-Life series has been renamed 'Half-Life: Episode 1'. Lombardi confirmed that this meant regular content being released over Steam, Valve's online distribution service.

Good news if you ask me. There's not enough in the Source engine for a whole sequel, but extra downloadable parts should be great.
