L4D2 "doesn't mean" the original gets orphaned, that was something they should have said at the time admits Valve. E3 is about "new titles," it's "not really a venue" for DLC or mod tools.
"We obviously listen to the community a lot," noted Lombardi, speaking with .
"That’s one of our staples. Did we anticipate it? No, we didn’t, but I think that one of the key things is: announcing Left 4 Dead 2 doesn’t mean we’re abandoning Left 4 Dead 1."
"Another thing is it’s important to remember that E3 is where you go to announce new titles, specifically titles that are coming to retail. We do press there, but it’s not really a venue for announcing DLC or mod tools," explained the studio bigwig.
"So I think there was a little bit of confusion that we created unintentionally, by announcing a sequel and not having the complete story ready: announcing it and not saying, there’s still a lot of stuff being worked on for Left 4 Dead 1, and the mod tools will work with both games."
There you have it, Valve still *heart* Left 4 Dead. The sequel arrives later this year on Xbox 360 and PC, see this year's E3 teaser trailer below.
