Kevin Feige said in a previous interview that they explored the concept of mutants.
After that, there were rumors that Marvel was working on a tentative film titled "Mutants."

Now, there is another whistleblower k .c. Walsh revealed on the change My Mind podcast that the mutant work Marvel is developing could be animated.
"I learned a bunch of filming times, Thunder Inc. in 2023, Nova in 2023, Fantastic Four in 2023, oakye's episode in 2023."
"There's another one I haven't said yet, I'll write an article about it, so I'm not going to tell you here, but I'll give some hints."
"It's crazy, it sounds really crazy. (Start humming the opening of the theme song of the X-Men Animated Edition)"
However, Walsh is not very sure of this rumor.
"I'm reaching out to more people and asking them, 'Is this real?'" Because I don't believe it myself, I don't know if it's new content or if it's a reboot..."
"A year ago someone said that the people involved in the production of a theme song were talking to a company. And I did hear that there's a possible animation project going on in 2023. ”
So, Walsh doesn't know if this possible animation project is a new X-Men story or a reboot of the old X-Men animation.
Of course, no matter what it is, it is good to have it anyway, and fans who are eager to see X-Men again say: We don't pick ~
