Fury stunned the boxing world in January when he made his retirement announcement after his second defeat to Usyk, but after making a series of comeback U-turns in the past - including teasing in a cryptic social media video on Monday (28.04.25) that people "know what's coming" after his former trainer SugarHill Steward said to Fury in a gym: "You know what time it is."
And in the wake of that hint, Dubois - who will be throwing hard-hitting blows in a thrilling undisputed world title rematch clash with Usyk at London's Wembley Stadium on July 19 - wants to meet the heavyweight in the ring.
He told Sky Sports News: "I think he's definitely going to come back.
"When I beat Usyk, I can fight him next. Who knows?
"There's so many great heavyweights at the moment. He'll be desperate to get back in the mix."
Usyk knocked out Dubois with a stiff jab in the ninth round of their heavyweight world title fight in Wroclaw, Poland, in August 2023 - although the Brit did floor his rival with a punch that was controversially ruled as a low blow - and the IBF champion has said he has become a better competitor since.
Dubois - who achieved a knockout win against Anthony Joshua in September 2024 at Wembley Stadium - said: "You can see from my last three fights I've come on massively, leaps and bounds.
"From [fighting] Jarrell Miller, [Filip] Hrgovic and then Anthony Joshua, I'm a totally different fighter now, a different man."
And Dubois - who stares at Wembley Stadium's arch and visualises his fight against Usyk as his fight mode ritual - has promised fans that they are going to see something "really special" as he makes his attempt to become the first British heavyweight undisputed champion since Lennox Lewis.
The boxing sensation - who is looking to bag WBO, WBC and WBA titles when he steps into the ring with Usyk - said: "You guys are going to witness something really, really special.
"The first [British heavyweight] undisputed champion since Lennox Lewis, I can't wait to do it."
