Very few details about “Avengers 4” have been released online so far, which is frustrating for the fans. Finally, there is some news about when the first trailer of the film will be out, and the wait will not be a long one.

According to a report by ScreenRant, Marvel Studios President Kevin Feige revealed when the trailer of “Avengers 4” will be released recently. Feige was speaking at the special screening of “Black Panther” where he was asked about the trailer of the upcoming film.

The trailer will be released “before the end of the year,” Feige reportedly said. That means the wait will not be more than two months.

There have been multiple theories about what the plot of the next film will be about, and the report notes that the fans will finally have some clues about the movie in the official trailer, on which they can base their new theories.

One popular theory about the film is that there will be some form of time travel involved for the heroes, to fix things after the devastating events in “Infinity War.” The trailer should confirm these theories.

The fans are also eagerly waiting for the title reveal of the film, which may happen along with the trailer release. The title is apparently considered a spoiler, which is why it hasn’t been revealed yet. This too should give a clue about what will happen in the movie.

One reason why the trailer or the title of “Avengers 4” hasn’t been released so far is that Marvel didn’t want the fans’ focus to shift away from the other movies that are releasing, especially “Captain Marvel,” which will be out by early next year.

“Avengers 4” is set to be released on May 3, 2019 in the US. The producers are yet to announce a release date for Australia.
