Marvel Comics Teases Death In Fall 2013

Marvel Comics has released a rather cryptic teaser image. The image simply has the Marvel logo followed by the words "Of The Dead" and the date "Fall 2013." Of course, "Of The Dead" could mean a lot of things. The first thing that springs to mind is that Marvel Comics probably plans on killing off a major character. However, "Of The Dead" really sounds more like a zombie movie than the death of a specific character. Could it be some type of zombie limited series involving Marvel Characters?
