Thanks to Press Start, an image of an internal change log at Valve has been leaked which supposedly confirms that Valve are working on both Left 4 Dead 3 and the Source engines replacement, imaginatively named Source 2 for now at least.

As a huge fan of the Left 4 Dead series and pretty much everything else Valve does, I’m excited about this news. But…and this is a big stinky but, isn’t there another game with a three on the end of it’s name that you guys should be working on Valve? I think I speak for the entire gaming community when I say where the hell is Team Fortress 3?

What do you think about this leak? Legit or just someone with too much time and Photoshop on their hands? If it’s true are you excited for Source 2 and Left 4 Dead 3? Let us know in the comments below.

Update: More evidence of Left 4 Dead 3’s existence has emerged here.
