Heyyyy, don't be so negative. There is activity being put into the making of it. I mean by that: I think they are working on trying to get the people interrest at first. They did polarlights ecto1a, they did a comicbook, maybe they will release the rgb dvd, they made a ghostbusters boxset, action figures (gozer, slimer, staypuft, terror dogs) and now halloween costume!
Two years ago, a five years old knew what costume I was wearing and not his parents!
So I think we are in the good direction for a new movie in the years to come. All is about money in the industry. When the movie industry will drain all their upcoming project, they won't want to do another zoro, or else. They'll want a blockbuster and Ghostbusters is that kind of movie.
