Just a reminder this movie was announced at the same time as Eternals, Shang Chi, Black Widow, Thor Love and Thunder and Doctor Strange 2 all of which came out years ago, despite a pandemic.
Movies get stuck in development hell all the time. It took 12 years of development for the first Spider-Man movie to reach the screen. So delays or director departures don't necessarily prove that a movie won't eventually get made.
