This won’t come as much of a surprise given that the film is scheduled for release at the end of April (or early May for those in the U.S.), but Marvel Studios chief Kevin Feige has confirmed that the first trailer for Avengers 4 will be with us “before the end of the year”.
Feige was speaking at a special screening of Black Panther, during which he also confirmed that Guardians of the Galaxy Vol. 3 is “on hold” following the firing of James Gunn, and that Namor the Sub-Mariner could make an appearance in the Marvel Cinematic Universe, although the powers that be are still deciding if and when that might happen.
OK, here we go, 3 quick questions, answers direct from Kevin Feige's mouth
1) AVENGERS 4 trailer "before the end of the year"
2) Namor COULD make an appearance, still deciding IF & when
3) GUARDIANS 3 status "on hold"

The first trailer for Avengers: Infinity War was released on November 29th 2017 on Good Morning America, and so we can presumably expect the Avengers 4 trailer to land around the same time next month, or early December at the very latest.
An unprecedented cinematic journey ten years in the making and spanning the entire Marvel Cinematic Universe, Marvel Studios’ “Avengers: Infinity War” brings to the screen the ultimate, deadliest showdown of all time. The Avengers and their Super Hero allies must be willing to sacrifice all in an attempt to defeat the powerful Thanos before his blitz of devastation and ruin puts an end to the universe.
