Is there any tentative schedule for this fight to come?
Ticket sales would be the least of the problems for this fight. This is Fury-Wilder III. Tickets would definitely sell like hotcakes. But I bet there would be a limited number of them for live viewing due to physical distancing requirement, if they are given the green light to proceed staging the fight with a live crowd.
If not, then I bet the pay-per-view buys would be making staggering high numbers. The Fury-Wilder II got at least 800,000 pay-per-view buys. This third match, if live viewing is not allowed (boooo), might even make a 6-digit figure.
If he said that then its clear that they do go after for ticket sales - gate as you mentioned but they wouldnt able to know if they wont try about having that PPV thing.
This is business but they should consider on the current situation we are in. Its not really that easy to imply on the things that they do like nor prefer.
When it comes to profits then we can see the difference but whats more important is that this fight should really be resumed and accept on what revenue they would able to generate on this one.
