The sports for 2028 have already been decided. Flag football, baseball/softball, cricket, lacrosse and squash will be added. Breaking will not be included.
At that rate, Pickleball will be added in 40yrs - "Oh yeah I remember back after the Covid Pandemic, Pickleball was popular", says 60-70yr old person.
Don't forget that modern pentathlon is dropping the equestrian portion and replacing it with a ninja-warrior obstacle course.
Running, swimming, fencing, shooting, obstacle course.
Still waiting for pankration's comeback and the addition of Quake 3 CPMA, though.
Though tbf, I'm not sure any competition with an artistic element belongs in the Olympics. I would ditch stuff like figure skating and synchronized swimming. Gymnastics can stay, but I'd prefer it be more standardized.
