As far as Guardians of the Galaxy Vol. 3 goes, it’s also basically a huge question mark at this point.
Gunn has also said on multiple occasions that Vol. 3 will be his final Guardians movie, although that’s not to say that certain members of the team couldn’t keep appearing in the MCU under a different filmmaker’s guiding hand.
When we last left off with these characters at the end of Avengers: Endgame, they were departing Earth with Thor, and Peter Quill was specifically interested in finding the time-displaced Gamora.
While the Guardians will have some role to play in next year’s Thor: Love and Thunder, it doesn’t sound like they’ll be in the movie that long, meaning the Holiday Special and Vol. 3 will be the next time they’re properly spotlighted.
