Did you expect the negative reaction from some fans following the announcement of Left 4 Dead 2?

"We obviously listen to the community a lot. 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. 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."
