If a photo of an internal Valve changelog list is anything to go by, we'll have a third installment of Left 4 Dead before we hear anything about that other Valve game we desperately want news regarding. The image bove was taken by a group of Dota 2 players lucky enough to tour Valve's offices recently as part of the International 3 Dota 2 tournament. If you look closely, you'll notice a reference to "L4D3" as well as "Source2", which appears to indicate that the game will use Valve's long in development new engine.

For an engine that feels like it's been around for half of my life, Valve's Half-Life-2-powering Source Engine could be doing a whole hell of a lot worse. Even so, the likes of Portal 2 and Counter-Strike: Global Offensive probably aren't pushing your PC to take up a part-time job as a very large, angular stove top.

Point being, Source is past its prime, and gamers want to see what magical crowbar-rendering tech Valve can pull out of its hat next. According to Chet Faliszek, however, Valve's in no rush to make another big leap any time soon.
