Update 4: Marvel has released Avengers: Infinity War's full-length trailer.

Update 3: Marvel has confirmed the trailer will arrive Friday, March 16.

Update 2: A behind-the-scenes look at Infinity War will air on ET on Monday, March 12, which means a new trailer will be coming sometime this week.

Update: Avengers: Infinity War's trailer hasn't released yet. Since the film is now slated to hit theaters worldwide on April 27, Disney should be releasing the trailer sometime this week ahead of A Wrinkle in Time - possibly on March 7/8 considering that Christopher Robin is also getting a trailer this week.

Fans are anxiously awaiting new footage from Avengers: Infinity War, so the question is, when will the official trailer release? The upcoming team-up movie comes from directing duo Anthony and Joe Russo, and it's arguably the most anticipated superhero film of all-time. It's the beginning of the end for the first MCU saga, culminating the past 10 years of storytelling within the Marvel Cinematic Universe.

Avengers 3 brings the Earth's mightiest heroes together, along with the Guardians of the Galaxy, for an ultimate showdown with the Mad Titan Thanos (Josh Brolin). Because of that scope, the film incorporates upwards of 40 Marvel superheroes and 76 major characters from all corners of the MCU. The first Infinity War trailer that released in November showcased some of those big names, but fans are waiting for the new trailer to shed some light on the story. And with only a few months left before the film hits theaters, the second Avengers 3 trailer should debut quite soon... but not as soon as fans would hope.

Unfortunately, it looks like Marvel will be skipping the release of Ryan Coogler's Black Panther and instead be dropping the Avengers 3 tease next month. We predict that the full-length trailer for Avengers: Infinity War should release in late February/early March leading up to the release of Ava Duvernay's A Wrinkle in Time - Disney's next live-action film. Given that A Wrinkle in Time is Walt Disney Studios big non-superhero film of the season, it stands to reason that the second trailer will debut with that movie.

The main reason for predicting this is that releasing in late February and early March fits within Marvel Studios' marketing timetable for past films. While the second trailer for Joss Whedon's Avengers: Age of Ultron debuted on ESPN in early January 2015, the final trailer released on March 4 - just about two months ahead of its release. A trailer for the Russos' Captain America: Civil War also released on March 9, 2016, while Marvel put out the final trailer for James Gunn's Guardians of the Galaxy Vol. 2 on February 28, 2017. All three movies released on the first weekend of May - and so does Avengers 3.

Since Marvel tends to put out their trailers in the early part of the week, it seems that the second/full-length trailer for Avengers 3 will debut either on February 27/28 or March 6/7, most likely on one of Disney's channels - ABC or ESPN - to capitalize on their corporate synergy. If the trailer doesn't release on one of those days, then the most likely option will be that Marvel waits a week to deliver the trailer ahead of Roar Uthaug's Tomb Raider reboot, which caters to the same crowd as the Avengers films.

It's curious as to why Marvel is waiting so long to show the next trailer for Avengers: Infinity War. Sure, they put out a short, 30-second teaser during Super Bowl LII, but that was mostly filled with extensions of scenes that were already shown in the first teaser. While they may want to hold off on revealing too many details for a movie this big, and they already know millions of people are going to see it no matter what, general audiences still need to get a taste of the film for themselves before they commit - and time's a-wastin'.
