The location of the dream fight between Anthony Joshua and Tyson Fury appears to be the biggest sticking point before it is finally agreed.
The former world heavyweight champions appear closer than ever to settling a rivalry which has stretched back over a decade.
November has long been the planned timeline. Turki Alalshikh is behind the venture, and Netflix are on board as the broadcaster. Fury outboxed Mariusz Wach a day before Joshua was dropped, then stopped, Kristian Prenga in their warm-up bouts.
But will Joshua vs. Fury be held in the UK or in the U.S.?
London calling?
London's iconic Wembley Stadium remains the preference for Joshua's promoter Eddie Hearn, and for UK fight fans.
But to suit a global TV audience, a 2 a.m. local time (9 p.m. ET and 6 p.m. PT) was mooted by Alalshikh.
Wembley has an 11 p.m. weekend curfew so an exemption would be required from the London mayor and Brent Council, who told ESPN that Wembley's safety advisor council must also approve.
A spokesperson for the Mayor of London, Sadiq Khan, previously told ESPN: "London is the sporting capital of the world and the Mayor is working to bring more of the world's biggest events to the city.
"Sadiq has made clear that London would be the perfect place to stage the long-awaited bout between Anthony Joshua vs Tyson Fury and the Mayor stands ready to support ambitions to bring the event to our capital as we build a better London for everyone."
This week, Hearn told Sky Sports: "I'm not going to sit here and tell you there's no way the fight's happening in America because things can change.
"But I really feel strongly that this is something that should happen in the UK and we'll do all we can."
Reacting to reports that the fight could head to New York's Madison Square Garden, Hearn said: "We're up against it -- it seems like everybody else has agreed but Anthony Joshua. He feels a little bit of responsibility to UK fight fans as well, and he's doing everything he can to give them what they want.
"We will try and make it as financially unviable as possible to do this fight in the U.S., so that hopefully they just turn around and say, 'okay, let's just do it in the UK.'"
Joshua's side signed a contract stating the fight against Fury must take place in the UK so any change to the location would require a renegotiation, Hearn has explained.
Hearn also insisted a news conference for Joshua vs. Fury will take place before the end of August, and they remain on course to fight in November despite the lack of an agreed location.
New York, New York...
Fury's long-time promoter Frank Warren was asked by The Ring if he understands calls for the fight to be staged at Madison Square Garden in New York, replying: "Of course I do."
Warren added: "But Sela contacted Wembley Stadium and asked if they would push the time back and as far as I understand, that's not happened. At the moment, I cannot comment on the date or location of the fight, that's going to be up to His Excellency Turki Alalshikh to announce when he's ready to announce."
A 10 p.m. first bell in New York on a Saturday night is equivalent to 3 a.m. the following morning in the UK.
Warren agreed with Hearn that the planned November date is not in jeopardy.
"The fighters will just need to get into training some time in September so that is what will happen in early September," Warren said. "They will be ticking over at the moment, I'm sure.
"I can only speak for Tyson but he is with his family. He has been in two training camps after being out for a long time so he is spending some time on the Isle of Man with his family and then as soon as the date is announced, he will get down to the serious business and bring in sparring partners and prepare for the fight.
"I believe the fight will go on in November."
