I'm assuming it's still not complete because there's still no news about a developer SDK (I'd assume they'd love to rake in engine licensing as soon as possible)
>Furthermore Source 1 didn't really get outdated as such, it got iterated on numerous times before introducing Source 2, which I assume will not be "completed" until Source 3 gets named the next version.
The main outdated thing about Source 1 is the authoring tools, which haven't changed much since Half Life 1 was released. Source 2 is supposed to fix that.

Source does rely on several other technologies (i.e. Miles, Blink, Havok) that you must license from their respective license holders, however Source is free to use if you're distributing on Steam and you only need to license the Source Engine for distribution off Steam or if you choose to distribute the SDK's tools with your game.
So with that in mind, I doubt the rely much on licensing fees as a source of revenue.
