Kevin Feige says more female led Marvel movies are coming. Captain Marvel is a gimme. We know the wheels are turning on the Black Widow prequel. What else do you think is likely? She-Hulk is always on my wish list. Ms. Marvel (Kamala Khan) is beloved by the fandom, she's up there. Squirrel Girl? Eh, but they're putting her into a show instead of a movie. Have Iron Heart replace Iron Man maybe? Tricky, all their greatest female superheroes are parts of teams, so you have to have the team origin before you can do spinoffs. Not very many you can hit the ground running on a standalone with.
