Following a previous webbed '4' teaser, Marvel Comics has released a new teaser featuring the number '3' in the same style.
This calls into question the previous assumption that the '4' teaser could have something to do with the connection between Spider-Man and and the Fantastic Four - and also what Marvel may be counting down to.
Marvel Editor-in-Chief C.B. Cebulski offered some commentary on the countdown teasers, but no insight as to what they will lead to.
"Wait, so it's not a Spider-Man/FF crossover?!? You mean, it's not a comic adaptation of Spider-Man 4?!?" Cebulski tweeted. "I told you, you will not see this one coming!"
Marvel produced a similar countdown campaign in March 2018 to announce the return of the Fantastic Four in their own ongoing series.
At this rate, whatever these are counting down to will be revealed on Thursday.
