I will stay with my theory:
Volume 101 ended with chapter 1025
In volume 102 we will have the conclusion of Sanji vs Queen and Zoro vs King. After that Oda will focus on Law & Kid vs BM and the roof fight
The Beast Pirates/only the Calamities will be on the cover
Volume 103 will be conclusion of the fights and we will get ZKK
The cover of volume 103 will be a new version of volume 3
