The solicitations are CLASSIFIED still.
However I do understand that it may be considered a very media-relevant comic. So probably spoiled two days previously by the New York Post or what not. It's expected to be as big as the Death of Peter Parker or Johnny Storm, and the launching of Miles Morales as Ultimate Spider-Man in terms of media coverage.
Given the election timing, and the kind of politically edgy subject matter that the Ultimates go for, could it be a President assassination issue? Again?
Blind guess, but I've been close about these things before.
