So that would be 5 years between episode 2 and 3 right?
Yeah its kind of gay it took 6 years for half life 2 to come out, 2 years for episode 1, 1 year for episode 2 and now 5 for episode 3. The whole episodic thing has been a fail for valve when the definition of a episodic games is "faster games to market, as many high production titles often take anywhere from 2–5 years to complete - with episodic gaming, the wait time is often reduced to an annual or bi-annual basis".
