Of the two still coming in 2021, Hawkeye and Ms. Marvel, I expect us to get Ms. Marvel before Hawkeye for two reasons. First, set photos for it started leaking months before anything from Hawkeye did. And second, it has been revealed that Hawkeye will have ties to the next Spiderman film and will start on Disney+ close to the release date for that movie, which is a Dec release.
Also from the rumor mill, Charlie Cox was supposed to play Daredevil in the Hawkeye series, but scheduling conflicts prevented it, though is he still supposed to be in the next Spiderman.
What I wonder about the Ms. Marvel series is whether America Chavez will debut there too, or if they will save her first appearance for the next Captain Marvel movie. Those two characters are friends and work together in the Secret Warriors cartoons, along with Squirrel Girl, who sadly never got her teased series. The Secret Warriors also work with Captain Marvel sometimes, so I wonder if that movie will include the Secret Warriors. Also, the dog from the Inhumans, Lockjaw, stays with the Secret Warriors, though I don't remember now why he is there and not with the rest of the Inhumans.
Edit: to add, Florence Pugh will also be in Hawkeye, reprising her Black Widow character. Some rumors are that she may be recruiting Hailee Steinfeld's character to join Val's team.
Edited for wrong group name.
