2019 and later will have 8 teams. 2018 at WF is the last 16 team event
I am a little surprised that Lake Nona was chosen to host two events, because the chances of UCF making the final 8 is extremely small, so attendance will be a disaster.
Picking Okla State and Illinois is also strange as their chances of making the final 8 are also slim.
With only 8 teams just about anyone can host if they have 6 indoor courts, so why not just give it to the top seeded team every year, so that at least the locals will attend and also separate the men and women's events. No offense to the women but their attendance borders on zero ( the men only do a little better) unless the home team is playing.
