Both of these seem rather obvious to me. The first teaser, "The End" has to be Spider-Man related as besides the fact that further details will be revealed at the Superior Spider-Man panel at New York Comic Con, Camuncoli has been a long time artist on the series even prior to it changing to Superior Spider-Man. I personally believe it will see the last stand of Otto Octavius as Spider-Man, and given the fact the teaser is in purple I believe it will be at the hands of the Green Goblin as with the build-up in recent months it is going to happen so why not then. The other teaser, " Global" has to be a continuation of the Avengers seeing them get a new team which will have members from around the globe.
