I feel like I read an interview or two with Destin Daniel Cretton where he says he still wants to do a second film but hasn't gotten to it because of other projects (initially Avengers, then Brand New Day and Wonder Man). Since he's one of the main reasons why the film worked so well, I'm willing to wait for his availability for a sequel. I rather wait for the right script and for everyone's availability to come together to produce another excellent film instead of rushing another one out to satisfy the masses.
I felt the same thing with Wakanda Forever and Ryan Coogler as I do here.
