Well perhaps not quite, given that Valve's second magnum opus Half-Life 2 hasn't even got an official release date yet, though we're fervently hoping it's going to be sometime this year.
However, according to reports circulating widely on the 'Net, Valve's Gabe Newell has already confirmed the existence of Half-Life 3 and revealed the first details on the title in an interview with Swedish games journalists - who have gone and well and truly let the Half-Life 3 cat out of the bag.
During a recent briefing at Valve's Seattle HQ, Newell is said to have revealed that the company is already in the planning phase for Half-Life 3 and is considering making Alyx Vance - NPC and Gordon Freeman's female sidekick in Half-Life 2 - a playable character.
Newell is also alleged to have promised even more alien-based revelations for the third instalment of the all-conquering FPS.
Perhaps predictably our enquiries to Valve were met with a bluff, "No comment". But it doesn't exactly take gaming rocket science to predict that a third instalment in the shooter series would appear somewhere down the line.
To learn that it might feature a character we've only seen in a couple of screenshots is a pleasant though not exactly compelling bonus. Further alien antics? Quelle surprise...
