MCU: Predicting Every Marvel Movie From 2020 - 2022
3. February 18, 2022 - Captain Marvel 2
It's tempting to actually put Namor in this release date instead, as such an early slot (February/March) has only been used so far for new properties (Black Panther and soon-to-be Captain Marvel).
However, the fact this is almost exactly three years after the release of the first Captain Marvel movie suggests it'll be when we see the sequel, especially if the debut is a big success - which you'd expect it to be, really.
The first film will be set in the 1990s, but either the events of that, a post-credits scene, or Avengers 4 will likely bring Carol Danvers into the present day. The character will almost certainly be a big part of any new Avengers team, and this is a great way of setting that up and indeed leading straight into it, especially considering what it might be about and the Skrull War taking place in the first movie.
