Never mind the fact that "Avengers 4" is still several months from being released -- there's been a plot twist.

Marvel Studios President Kevin Feige assured fans in late October that the upcoming film's trailer would arrive "before the end of the year," but now that doesn't look so certain. Joe Russo, who directed the film alongside his brother Anthony Russo, has complicated everything we thought we knew. During a Q&A on Thursday, Nov. 8 in his Los Angeles bar Duello, Russo indicated that the trailer might not actually arrive in 2018, as Comicbook.com reports.

"When can we expect to see the Avengers 4 trailer?" the director said. "You may or may not see it before the calendar turns to 2019."

Apparently, the editing process is such a huge undertaking that they're only about halfway through. Russo said they're "really just scratching the surface" on their visual effects shots, and there are "more than 300" in the superhero flick. They've also only begun to work on the score, he said.

There are still nearly two months left in 2018, so fans can keep hoping for a trailer sooner rather than later. That said, you may not want to count on Feige's earlier guarantee; a lot of work still has to be done.

At least there's still an official title reveal to look forward to. We expect that will still come by year's end.

"Avengers 4" is scheduled to open May 3.
