In light of recent events, Time to speculate.
No Kita Rio Announcement on 1st of the month, so her contract did not end on June 30th. Some say it's because of the HULU show.
The Oda grad announcement came a week early on the day which should have given us Kita Rio's fate.
Niina Joins J=J in a surprise announcement, so no Uta-hime replacement for Oda.
These two seemingly rushed announcements make be believe that there is a bomb about to be dropped in the H!P-verse.
No Oda grad in the fall means that J=J Yoko Arena is a done deal
The Niina news and Oda news makes me tend to lean Kitagawa returning to MM.
