Valve's Tristan Reidford has lightly teased Left 4 Dead 3 in a tutorial for the Destinations Workshop Tools. The eighth image in the tutorial, titled "08_directory_fun.png," showed a conveniently placed folder called "left4dead3." From the pessimist's perspective, this was just a mistake. It's funny, though, that the folder viewport was scrolled in such a way that left4dead3 was shown first. According to Tristan's Valve Developer Wiki contribution history, the image was first uploaded on June 28, and then about 24 hours later - after the community had been teased - it was replaced by an edited version to remove the Left 4 Dead 3 reference.
