Nothing too crazy. This is how it compares to my guess.
GUESSES -
ACTUAL
King 1.330 billion - King 1.390 billion
Who's Who 550 million - Who's Who 546 million
Black Maria 320 million - Black Maria 480 million
Sasaki 350 million - Sasaki 472 million
Ulti/Page 1 250 million - Page 1 290 million/Ulti 400 million
Who's Who I guessed exactly. King slightly off, but around that range. I made it clear only Who's Who is going to surpass Izo.
Why would Black Maria have a 500m+ bounty at 29 years old, when Izo has a 510 million bounty at 45?
The only Tobi Roppo who will surpass Izou is MAYBE Who's Who. But even that I'm not sure of.
Page 1 at 290 million seems about right, because of his age. I'm a little surprised at Ulti/Black/Maria and Sasaki. They're about 100-150 million higher than I expected, but again nothing greatly higher. I'm surprised Black Maria > Sasaki though. Is that because she was born in Wano?
