Honestly though, we're looking at a ton of new series in a few months.
U19, Poro, Samon-kun, and Hinomaru Sumo are all in their last stretch.
We Never Learn and Hungry Marie are possibly in danger.
Gintama shouldn't have too much left.
That's seven spots that could all open up around the same time. Could be cool for Jump to do another huge serialization round and maybe things will stick.
Also no guarantee that Dr. Stone or Robot x Lazerbeam will stick around.
Spring Weapon #1 is getting treated like a Hinomaru Sumo so I think it's safe due to editorial love.
