It's unprecedented for a blockbuster movie to get this far into development without so much as an official title and teaser trailer but Avengers 4 doesn't need to play by the Hollywood rulebook. After Infinity War's cliffhanger, the fans will show up in droves to see the sequel, regardless of what they've seen in advance.
According to Marvel Studios head honcho Kevin Feige, the title was kept under wraps because it's a "spoiler", but so many months on from Infinity War and the shroud of secrecy is yet to be lifted. Ant-Man and the Wasp came and went offering no clues.
Feige, however, went on record with Collider to confirm when we might learn what Avengers 4 is actually called, and the good news is that it won't be too long from now.
"That'll be after the Captain Marvel teaser probably, announcing that title. It'll be towards the end of the year with however we launch that film."
So, there you have it. Towards the end of the year, there's a good chance the fans will be able to refer to this movie as something more than "Avengers 4".
