One Of Swords notes that "Something’s up at callofduty.com," and sure enough, heading to the website for the military shooter series indicates that something is indeed up. What exactly is unclear, however, as there is a vague image constructed from user photos, implying there's something viral/social happening (maybe a flu outbreak at a cocktail party?). The image has a ghostly quality, which ties into some current rumors. Presumably there's more on this to come.
