About the ending stuff, i actually bet that Time Paradox will end in the issue after Bone Collection, this chapter gave me the cancellation vibes.
Overrall, mixed feelings towards it, i think editorial could maybe chill out a bit, we're just entering August and they will already easily surpass 12 new series in the fiscal year, cancelling BC and TPG under 16 chapters feels a bit unnecessary to me, unless they really need the spot for a popular veteran returning with Kubo or maybe Togashi returning, but that i think they could give a bit more of time for these 2, even more as cushions for the 4 series that are starting to rank in the toc with next issue, but well.
About Mitama, is really weird because this chapter didn't gave any sign of ending in the next so i wouldn't rule out a potential "moving to Saikyo or Plus", because what was the point of making everybody believe the series were ending in that last arc just to end some chapters after out of nowhere? lol
Btw, if Mitama is "ending" on 36/37 so is very possible that we will already know the new series in the preview of 38 this week.
