I've seen some "concept shots" from the new engine they "plan" to use, and from the screenies I've seen, Half-Life 2 Episode 3 might look pretty good. Hopefully however, Valve does release a confirmation for this game, because it would be great!My only worry mate is the engine
they need to move on with the game engine now
as great as it was its really time to move on - and maybe this is the cause for the delay
they are gonna shock the world with some crazy ass new half life game engine!
i'm thinkin something like the frostbite 3 engine
