Talking to Kotaku in a video podcast, Valve's Chet Faliszek as good as confirmed that downloadable content is in the works for Left 4 Dead.
Faliszek told viewers to expect an announcement soon. "We have the DLC coming, we're going to do the 360 at the same time as the PC," he said.
Faliszek didn't say what form the DLC would take, but said that Valve was focused on "more content you can play".
You won't have long to find out - the DLC was due to be revealed before Christmas and has only been held up by Valve staff taking some time off. "If it wasn't the holidays and people weren't taking all these vacations here at Valve, you'd have seen that announcement already," Faliszek said.
"On the PC side we have the SDK coming out," he added, so the mod community can look forward to making its own Left 4 Dead content soon.
More when we get it.
