ValveTime has dug through the Source Filmmaker code to reveal references to "Source 2," reportedly a next-generation revamp of Valve's famous game engine. Given that the three major consoles are all due a refresh, it's unsurprising to see preparations being made. That said, however, the second (and major) launch title for the original Source was Half Life 2, so we're gonna be getting a complaint letter ready if we don't get some more time with Gordon, Alyx and Dog in a beautifully rendered future dystopia.
