Avengers 4: 9 Things We KNOW Will Happen

3. Thanos Will Return

Depending on how devastated you were after the end of Infinity War, following that post-credits scene with even Maria Hill and Nick Fury dying too, you probably left the theatre.

Stay a little LONGER though, until after the final Marvel logo appears, and you get the text, "Thanos will return".

It's very much connoting "The Avengers will return" from 2012's release, and is a nice role-reversal to insert Thanos as a really historic, important character.

Marvel likely know they've messed up with pretty much every villain outside of Obediah Stane, Loki and Killmonger, and despite his mission being complete, we can firmly say getting revenge on Thanos is Avengers 4's major driving force.
