Looks like we are finally partly back in OG qualification system 80' :
1 host USA
5 Continental champions 2026 (old system)
3 World Championship 2027 best teams not yet qualified (v.good idea - in the past World Champion was always directly qualified)
3 World best FIVB ranked teams (Nation League will be also important)
My personal feeling - Continental Championships and World Championships will be finally on high level motivation and no additional qualification tournaments consuming time and decreasing value of core Championship tournaments.
