IBF champion Filip Hrgovic made his intentions clear, entering the ring after Dubois' victory, with both keen on a rematch.
Dubois stopped the Croatian in June 2024, but Hrgovic has since rebuilt his reputation, claiming the vacant IBF title with victory over British prospect Moses Itauma in August.
But Hrgovic, 34, has Cuba's Frank Sanchez waiting as a mandatory challenger.
Promoter Frank Warren is working towards staging Hrgovic's first defence in Croatia early next year, potentially delaying a reunion with Dubois.
The biggest financial prize for Dubois could be a meeting with the winner of Fury and Joshua's December showdown.
"All those names are there to do a unification fight next year and that's what we'll be working on," Warren said.
Wardley, meanwhile, has shown he can compete at world level, but the manner of Saturday's defeat exposed a gulf in technical ability.
A return against a lower-ranked opponent could help restore confidence, but questions remain over whether Wardley can make the adjustments needed to challenge the division's elite again.
American Jarrell Miller remains highly ranked, while compatriots Jared Anderson and Richard Torrez Jr, an Olympic silver medallist, are rebuilding.
New Zealand's former world champion Joseph Parker is seeking a return after his provisional doping suspension was lifted in August.
Australia's Teremoana Teremoana has stopped all 12 professional opponents within two rounds, while Uzbekistan's two-time Olympic champion Bakhodir Jalolov extended his unbeaten record by beating Solomon Dacres on Saturday.
In Britain, Derek Chisora, 42, is considering another comeback and says he expects to face WBA 'regular' champion Gassiev in December.
British champion Richard Riakporhe is pursuing world honours after moving up from cruiserweight, while former cruiserweight world champion Lawrence Okolie is targeting a return after reaching an agreement with the WBC over an adverse drugs test finding.
David Adeleye, Dave Allen, Johnny Fisher and Frazer Clarke remain on the domestic scene, while Leo Atang, 19, and Ireland's Adam Olaniyan, 20, are emerging talents.
With Usyk, Fury and Joshua approaching the ends of their careers, the heavyweight division is entering a new era.
There is no shortage of potential big fights, but bringing the champions together before mandatory obligations, rematches and boxing politics get in the way could prove the greatest challenge.
