Left 4 Dead 2 boycott group repsonds to Valves response

First Left 4 Dead 2 was announced, then a group of 15,000+ formed to boycott said game, then Valve responded to the boycott and now the group has responded to Valve.
“While we are excited about the idea of new content, we are still in the dark about it. What sort of content is it? For all we know, it could be a new main menu screen. Is it a new map, is it new monsters, is it new weapons, etc…? We’d like to know what is going to be in this new content.
Furthermore, when will this content be released? Is there any sort of timetable within which the content will be made available? These are all questions we would like Valve to elaborate on.
Last, Valve is trying to address the community split from releasing a new game in the series… they did not go into details, and are still working on it.”
I mean I don’t really blame them for giving such a stern response. Valve says that there will be new content for the original Left 4 Dead but exactly what kind of content and when, if ever, will this content hit? Let’s hope that Valve didn’t just tell the boycott group what they wanted to hear to calm them down as we will have a very unhappy community if that is the case.
