A couple of weeks ago I heard from multiple sources that a teaser trailer for Avengers: Infinity War would hit the internet around the first week of December and then in theaters with The Last Jedi.
This morning two big Infinity War things happened to make it look like the teaser trailer is imminent. The first is a series of Vanity Fair covers for an issue that will probably be on shelves during the first week of December, and then the Russo Bros posted this on Facebook:
Either they’re counting down to a trailer release in three days (which would be early), or the trailer could be hitting the internet on December 3rd. Previously a date of December 4th was being spread around, so this fits that rumor.
If it pans out that way, then next week will be a busy one of trailers as we’d get Infinity War to start the week and then it sounds like Jurassic World: The Fallen Kingdom will put out their trailer by the weekend.
