While these mysteries are no doubt intoxicating, the really important questions are the ones Valve will have been asking itself as Episode 3's development slipped further and further away from the release of its predecessor.

There are other burning questions, too: will the next release still be branded an episodic offshoot of Half-Life 2, or has it, as some fans have supposed, evolved into the grander form of Half-Life 3? Then there's the batch of recently leaked concept art, originating from 2008, prompting many to wonder whether the interdimensional Xen world will make a reappearance (possibly now reimagined as a tie-dye acid-trip featuring floating avioli and alien squid-flowers) and raising the pressing issue of what kind of ear-muffs Alyx will sport in the cold wastes as she hunts for The Borealis, an Aperture Science ship containing either humanity's salvation or its doom. But inquiring minds might find their own answers by playing through the preceding two episodes. If there's one question Valve must be sick of hearing it's this: where is Episode 3? No-one's saying anything - not yet.
