Last week, Disney's release slate was filled with movies all the way up to 2023 with promises of theaters full of Pixar, Disney Animation, live action remakes, and, most important to this list, Marvel movies. Disney has slated seven untitled Marvel movies for the next few years, leaving fans to speculate just what these titles can be. Phase 4 is anyone's game at this point, but there are some key sequels and titles that are certainly making the game.

It's important to note that Avengers 4, for whatever reason, is not included on this slate -- even though Avengers: Infinity War is. The untitled Avengers movie hits theaters May 3, 2019. And we have one official Phase 4 movie on the books. Tom Holland's Spider-Man: Homecoming 2 has a release date of July 5, 2019, making this the first movie of Phase 4. While release dates are always subject to change (as we recently were reminded), we do know a few other Phase 4 movies that are definitely coming. The rest is pretty much speculation, and while Marvel likely won't announce these titles until after Avengers 4, that can't stop us from guessing what's in store for the next few years.

Guardians of the Galaxy Vol. 3

Release Date: 7/31/20

Guardians of the Galaxy Vol. 3 is the only Phase 4 movie that's but talked about in any definitive terms, with James Gunn returning to write and direct the third movie in one of Marvel's top franchises. We know that the movie is aiming for a 2020 release date, but not the specific date. While Guardians is big enough to open in May (which usually has a high-tier Marvel movie), opening in July isn't a bad spot. Seeing as how Vol. 3 is likely further along in the development process than other projects, it'll hit theaters sooner rather than later. Honestly, I feel like Marvel is hiding a release date for May 2020, which would be an ideal spot for Vol. 3.

Black Panther 2

Release Date: 5/7/21

Oh, you better believe a Black Panther sequel is coming. This movie has dominated in just about every single way and Marvel is probably already doing everything they can to schmooze Ryan Coogler back into the director's chair. It's one of the biggest success stories in Marvel's filmography so they aren't going to be sitting on it for long. The typical waiting period between Marvel sequels is usually three years, so 2021 feels right. Putting the movie in May makes sense given how much it made in February, which used to be viewed as a kind of "off-season" for movies. If it did that well in an off-season, imagine what it could do opening the summer.

Black Widow

Release Date: 7/30/21

Fans (and Scarlett Johansson) have been asking for a Black Widow movie for years, and Marvel finally found time in their busy schedule to begin developing it. The project has a writer attached and while nothing is set in stone, a Black Widow movie has never been closer. With that in mind, July 2021 feels like the right spot. It's right in the middle of the summer season and positions Black Widow as a tent pole. The character is more than worthy of her own film and with the demand for more female-fronted movies stronger and louder than ever, it's time for Black Widow to take her spotlight.

Doctor Strange 2

Release Date: 11/5/21

No sequel has yet been confirmed for Doctor Strange, but giving Marvel's track record and the success of the solo film, it's a safe bet that it will be arriving in Phase 4. It'll have been five years since the debut of the first movie, which is a big gap, but the character will feature prominently in Avengers: Infinity War and Avengers 4, so it's not like he'll have disappeared from audience's minds. The Master of the Mystic Arts proved popular with fans and there's definitely more ground to explore in Strange's crazy world of magic and otherworldly forces.
