Team Fortress 2 Classic is an upcoming mod for Valve's shooter that aims to re-imagine the launch era of the original game and you'll be able to try it soon.
TF2 Classic already exists (not too many users though), but after Valve’s change in policies around TF2 modding, they will able to have a proper Steam release and keep building out the mod.
Is TF2 Classic going to be a separate product from TF2?
Yes, they even have a separate Steam store page.
