Half-Life 2 Episodes are the Third Half-Life

So in a recent interview, Gabe Newell of Valve commented that the Half-Life 2 Episodes, which began last week with Half-Life 2: Episode One, is really not an expansion to Half-Life 2 and should be considered Half-Life 3.

Considering the vast lack of new content featured in Half-Life 2: Episode One, that's not a very impressive beginning to a third installement. I also find the whole naming concept dumber than Doom 3, which really is the fourth title and a remake of the first.
