Hey, Tenipuri isn't THAT bad (I do have issues with the SQ Jump continuation, though - pacing there is, personally, godawful).
Aaaaaand, I this was sort of expectable to happen - how in Earth would you finish in 5 chapters just RIGHT when a gorilla wedding was in the middle of this "ending hype". Unless weird shenanigans, that's for sure.
What I DO expect from the Jump GIGA thing - probably another 5 or 10 chapters to conclude and wrap up everything (or whatever it takes to fill a whole volume). Hey, if Asou Shuuichi did so with Saiki K., I think Sorachi can make it too.
