Left 4 Dead 3 news

Does anyone know when will be the left 4 dead 3 pc game will be releasing?? I'm awaiting for it...!!!

Game hasn't been announced so its very unlikely that anyone knows the release date. You will be waiting a long time.

Left 4 Dead 3 hasn't been announced and we don't even know if it exists. Valve is good at keeping secrets.

wasn't it on some retail list or something at one point?

Well there have been rumors of its' existence with it being shown on Valve's Project tracker and found on listing during a Valve tour.

Again, it's all rumors and none of it is confirmed by Valve.
