With the latest teaser image from Marvel Comics, it's clear that Marvel is counting down to a big Spider-Man announcement, not releasing some version of Sam Raimi's Spider-Man 4.
Social media reactions are blasting Marvel for starting with 4 instead of 3, but the more logical assumption was that Marvel intentionally begun their countdown with 4 as a clue that the announcement will be some sort of Spider-Man/Fantastic Four team-up.
However, current Marvel Editor-in-Chief C.B. Cebulski has ruled out a Fantastic Four team-up, stating that the countdown will reveal something no one is going to see coming.
