User blog comment:GinIchimaru/596 - Sabo's return imminent?/@comment-2229670-20100821072136

Ace was one of Whitebeard's commanders, Whitebeard being the "strongest man in the world". Sabo could be one of Dragon's commanders, Dragon being the "most wanted man in the world"

And Luffy, he will be the next Pirate King. :))

Hope Sabo is alive... Maybe he will be met by Nico Robin since the precise reasons Kuma sent her there are unknown.
