I wouldn't be surprised if they hadn't even started making HL3 yet, and even if they haven't, I actually don't care. I'm not hyped for it, so I've got no expectations other than "As good as a Valve game". So as long as they spend the time to actually make something worthwhile and don't just through something out to appease to the crowd who cares how long it'll take? There's plenty other games out there and plenty other things to do in the meantime and you probaly won't die before it comes out anyway.
