Given the last fight was 60% Fury fans, 20% celebrities and the rest boxing fraternity, Wilder fans + general public it's going to be hard sell. Given you'll immediately lose 30% international Fury fans.
I wouldn't be surprised TBH. Wilder is so mentally fragile that an arch - troll like Fury won't resist taking a potshot if he can. Frankly I don't think he needs to. I think that Fury is so ahead of Wilder in all aspects of the boxing game except power, that if he just keeps his head and does what he does, he'll beat the daylights out of him.
They should have just done it in the UK. I reckon UK gate plus PPV outsells what this could do stateside.
It will have to be before October as the way this New variant is spreading here they'll be another lockdown by then...
