I think Zoro will defeat King on 1030, because on 1031 the focus will be on Onigashima Falling, as Yuderon already predicted with the numbers from the title
and it makes sense since we only have 5 minutes now, 5 minutes = 5 chapters
1027 - 1028 - 1029 - 1030 - 1031
but i do think on November, that would be chapter 1032 ~ 1034, we're getting something big for Zoro, and it could be a reveal from his backstory, perhaps Yamato revealing to Zoro that Ushimaru told her about a son or something. I think in those chapters Zoro could get his hands back on Shusui.
