I wonder if Wilder is really next but it will be a very interesting fight. It would've been bigger than Fury-Wilder when they were both champions and undefeated and for the undisputed. Still, better late than never. But we'll see if they are really going to face each other next. The WBC already mandated Wilder and Ruiz for the final eliminator which means the winner will face Tyson Fury which is not really cool if we see another Fury-Wilder.
Probably it's going to happen Joshua's promoter has been entertaining this fight but Joshua wants to regain his confidence so he opted to fight Whyte instead, so if he wins against Whyte and Wilder wins against Ruiz they will face each other, it's not good to see another Fury and Wilder fight, I prefer the Wilder Usyk match the heavyweight division has a lot of great fights coming and there's a lot of new faces and familiar faces coming for the title, expect exciting fights in the heavyweight division.
I have the feeling that Wilder is also yet recovering mentally from his back-to-back brutal losses to Tyson Fury. Though he might have won a first-round KO in his return bout against Helenius, he was the one running backward instead of the other way around. If not for that huge counter, Helenius would've been able to do some damage on Wilder. The Ruiz fight will determine if Wilder is really back to his usual confidence when he was undefeated. And if Wilder wins, he also needs to decide if he goes for AJ or he will rematch Fury for the fourth time.
There are a lot of good fights to happen in this division with Usyk-Fury for the undisputed belts as the biggest. Usyk after Dubois might also get another mandatory from the IBF against the undefeated Filip Hrgovic and the WBO if Joe Joyce wins his rematch against Zhang. Only a unification fight with Fury will excuse Usyk from his mandatories.
