Half-Life 3 And L4D3 In Development?
 

I know, I know, we are all probably being trolled for the billionth time but here's the link anyway. "I think it's kind of public knowledge that people know that it is being worked on, and so if I say 'yeah, I've seen some images, like some concept art of it,' you know, that wouldn't be big news. I guess I could say that I did see something that looked like kind of in the Half-Life universe. It wouldn't surprise anyone if I said 'yeah, they're working on it,' so I guess to go on a limb, I would say yeah, I did see some concept art for Half-Life 3."
