There's no way they won't have Storm on the team, which already makes one more black character than the first Avengers movie, and nobody really complained. I doubt they'll feel the need to make another major hero black, which is something they didn't do yet in the MCU.
Iceman being outed also increases his chance of appearing, since there's also no major gay heroes.
I also imagine they'll have a bigger number of women in the roster, probably 50/50.
