Damn, that countdown gave me anxiety af. Love how Sorachi acknowledged that there's no way to end a series when it's too busy doing a gorilla wedding, lol.

I wonder if MAL will set this manga as finished publishing and make the next chapters its own entry.
It depends. If the Jump GIGA chapters are in a separate volume than the WSJ chapters, and the title of the series changes, then it would be it's own entry. If it still is just called "Gintama" and are in the same volume as the other chapters, then it'll be the same entry.
Saiki Kusuo's last couple of chapters were published on GIGA, but those chapters were compiled with the last couple of chapters published in WSJ, so they didn't get a separate entry.
