I doubt King bounty going reveal in the vivrecard, hope we see it in this chapter or the next one.
Overall I think King going play a huge role, every calamity so far had their small own arc, their own "lead performance".
-Jack had his arc with the Minks where he was the "all star" as the major villian until the end.
-Queen had his small arc in act 2 where he was the "all star" in Udon, major villian and key point to caught Big mom.
-King going be the "all star" in the raid and doing something important soon too, like this:
At this point I wouldn´t surprise if King get 1.657B and burn later everything around Flower capital.
Imagine if King was a special agent under Kaido visiting prisons to gain members, like WsW get his Nika folklore by King xD.
