Well this is not based on any feats they may or may not accomplish in Wano (like ZKK, beating big mom, lunarian, etc.) but simply based on the observation that Oda has been hyping them up like never before in this arc. Wings of the pirate king, "stars of the show"...My gut feeling is that these are just foreshadowings for the greater things to come (yeah, no shit, foreshadow again,...I know not everything Oda does has to be foreshadow, but its not fun other way round). So anyway, I am willing to bet that both Zoro and Sanji will bet bounties close to a Yonkou (above blackbeard's, closer to Shanks').
Other strawhats will get bounties 1.5x or 2x the top ranked beast or big mom pirate they defeat.
Meanwhile, Luffy will at least surpass Whitebeard, possibly even Roger in terms of bounty. Post Wano this will be a crew of true king of the seas.
