Valve has definitively debunked rumours suggesting that a new Left 4 Dead game is in active development. In a statement to IGN last week, the developer said that it is "absolutely not working on anything L4D related now."
Rumours about a new entry in the zombie shooting series have been bubbling along for years, but resurfaced last week thanks to speculation from YouTuber Tyler McVicker and HTC China President Alvin Wang Graylin. McVicker correctly predicted the existence of Half-Life: Alyx ahead of its reveal last year, and recently suggested that Valve could have been at work on a new title. Last week, Graylin tweeted slides from his recent talk about the future of VR, suggesting that both Valve's "HL: Alyx/L4D3 will drive consumer and AAA studio interest." He later confirmed that this was purely speculation.

Valve says that while "we did briefly explore some Left 4 Dead next gen opportunities a few years ago," the developer isn't working on the series "and [hasn't] for years."
"It's clear that some people are having fun creating misinformation to spin up the community and other outlets. Unfortunately, for now a new L4D game is not something we're working on." If you're still looking for some zombie-killing action, however, Left 4 Dead's original developers, Turtle Rock Studios, are making their own spiritual successor, titled Back 4 Blood. It's still some way off, but at least you'll probably see it before Valve takes another pass at it.
