Well of course Valve's working on a next generation update to its long-lived Source Engine. What do you think Gabe Newell and co have been doing all these years, sitting on Left 4 Dead 2 DLC and dreaming up new ways to tease us about Half-Life 3?
Fansite Valvetime (the same outfit that leaked these Half-Life 3 concept artworks) has been chewing through Source Filmmaker script in search of buried intel. It calls our attention to line 1387 from the Pastebin & file path, whatever the hell that is: ''Return an str with the current engine version. If key doesn't doesn't exist, assume 'Source', otherwise invalid -- assume next-gen 'Source 2'.''
Could work on a next gen engine be the reason the next Half-Life title has been so long in development? It certainly sounds plausible, but given Valve's past antics, we wouldn't be surprised to discover that this is a massive prank. Somebody get Newell under CCTV surveillance. At the slightest hint of a cheesy grin, I'm pulling the site and emigrating to Canada. They know how to treat a man right, in Canada.
Half-Life 2 artist Viktor Antonov claims Valve is no longer as interested in "risky creative projects". Let's hope he's wrong.
