Following postponements of Avengers: Doomsday and Avengers: Secret Wars to December 18, 2026 and December 17, 2027 respectively, MCU enthusiasts have been speculating about the untitled Marvel project originally slated for July 23, 2027.
Assuming Marvel maintains this release window, it will become the sole MCU installment between the two Avengers films, with Spider-Man: Brand New Day now positioned earlier on July 31, 2026.
Fans have proposed numerous theories about this mysterious slot. "I believe Doctor Strange 3 is the strongest contender," commented one Reddit user in r/MarvelStudiosSpoilers. "Though there's an outside chance it could introduce the MCU's X-Men, depending on how Fox's X-Men characters factor into Doomsday."
Many supporters are favoring a third Doctor Strange installment as the frontrunner. "Probably Doctor Strange 3 in my opinion (though I'd personally prefer Shang-Chi 2)," tweeted one fan, while another speculated: "Part of me hopes Dr. Strange III could incorporate elements of World War Hulk." While intriguing, this seems unlikely.
"Doctor Strange 3 makes the most sense strategically between Doomsday and Secret Wars. Blade has clearly been delayed until after Secret Wars," argued another Redditor - though one commenter strongly disagreed: "Actually, Black Panther 3 is the most plausible option - Marvel and Ryan Coogler have openly discussed developing it for his next project."
Several fans noted BP3 was being overlooked despite compelling evidence. "Odd how everyone's discussing DS3 when there's been zero official discussion about it," observed one commenter. "Meanwhile Black Panther 3 exists as a confirmed project."
Multiple supporters rallied behind BP3 as a serious candidate. "It appears further along in development than other possibilities," noted one Reddit user. "My money's on either Black Panther 3 or (less likely) Doctor Strange 3."
"Black Panther 3 stands a real chance for that 2027 slot," asserted another user. "Nate Moore mentioned producing it before his Marvel departure, and Denzel Washington revealed they'd written him a role before the project was public."
However, one fan clarified the timeline might not align perfectly: "Moore has actually already left Marvel - he's even been cast on Survivor. He stated he'd return for BP3 production, not necessarily stay until release."

Some enthusiasts still hold hope for the troubled Blade reboot, despite setbacks since Mahershala Ali's casting announcement in 2019. "I suspect Blade footage was secretly filmed," claimed one optimistic user, while another joked: "Could it finally be Blade? Ha."
A more pragmatic commenter noted: "Whatever fills this slot will likely connect narratively to Doomsday and Secret Wars. Blade doesn't seem appropriate for that bridging role."
"I want to say Blade but realistically that's not happening," mused a Twitter commentator, suggesting an alternative: "Maybe a Young Avengers/Champions movie (though probably better suited for Disney+)." Another Redditor proposed: "How about a Midnight Sons team-up film starring Blade and introducing Ghost Rider, set during Battleworld?"
Interestingly, some predict corporate maneuvering: "Sony might claim that spot for Spider-Man: Brand New Day," tweeted one user, with another confirming: "Spider-Man: Brand New Day will likely shift there. End of story."
