adding middle school teams

Does anyone know if they are going to add more teams to the middle school world championships? There was 160 spots last year. I was wondering because it seems that there are a lot more middle school teams this year and growing fast. It would be great to eventually catch up with the high school with 400 spots.

Robotevents says that MS Worlds has 156 spots. I don’t know if this is just a minimum estimate, or if they’re only allowing 156 teams.
