It's coming.
We've all prolly read the same theories and stuff lol. There really is a lot of foreshadowing. And like I said when the chapter itself came out I think Gege gave himself wiggle room for an eventual comeback. Now it's just the matter of deciding whether he wants to or not.
But yeah from the Buddha links to the sign of Gojo's domain and it being linked to a deity that was the strongest and then got killed by Yama the King of Hell aka Sukuna and then came back and defeated it, to the lotus flowers, to Gege's recent drawings, connections with that Bobobo or whatever manga, unfinished business with Kenny and Geto's body. There is a loooooot.
