Fury's promoter, Frank Warren, standing near the two fighters in the ring, said an announcement will be made next week.
It's going off in Belfast, Northern Ireland.
Fury excelled in rounds 6-10 as he out-landed Pianeta 71-21 overall en route to connect leads of 107-37 overall, 7-1 jabs and 100-36 power.
Two-and-a-half years on and the duo's goading duel - which continued this week with Wilder crashing Fury's weigh-in - will finally be settled in the ring.

However, the pre-match press conference saw Maurizio Sarri having to discuss a potential high-profile departure yet again. We have to score from the chances we create and we have to look at taking those points into our next game".
Wilder will have seen little from Fury in his win over Pianeta to concern him before their proposed fight in Las Vegas in November.
A prelude of things to come was offered in Fury's victory lap, parading around the ring with Wilder's heavyweight title strap.
"At the minute it's a bit of a freak show with Tyson Fury", Bellew told Sky Sports.
"It is on", said the American, who holds a professional record of 40-0, 39 KOs. I know there's a big fight coming up between him and I, but this is the first and very important step for him. I said send me the contract, they sent me the contract.

I am happy with Mesut because he worked hard. "Today, with Auba, I know he can play". But also they had options, chances to score and effectiveness is the difference.
It was in the crowded reception area of Belfast's Europa Hotel, after the weigh-in was staged in a function room, that the 32-year-old Wilder then had his confrontation with Tyson Fury, the former WBA, WBO and IBF champion.
The first fight of his return was an nearly comical bout against Albanian cruiserweight Sefer Seferi in June, which ended after the fourth round when Fury's opponent quit. And if he ever thinks about having this belt, he better wake up and apologise to me because he'll never have this.
None of this could take place without Fury taking care of business against Pianeta, and that's exactly what he did while getting in some much-needed rounds. I'm here, baby. I just left the Fury weigh-ins and oh my god, was it insane! "I am going to knock you out".
"I got 10 rounds with a very tough man under my belt".
China 'likely training for US targets'
Beijing claims more than 80 per cent of the South China Sea, which carries around US$3.4 trillion worth of global trade each year.
Fury's second fight in as many months lacked drama, and some fans jeered at the end - but the former champion was happy to shed some more ring rust.
