Pacquiao, 36, is set to stand for the Filipino senate next year, so his next fight will be his last.
The eight-weight champion told AFP earlier in October that he would announce his opponent for the fight in November or December.
Amir Khan has already revealed that he is one potential opponent but Pacquiao whetted the appetite of many a fight fan with the revelation that he is back in talks with Mayweather.
“I don't know yet who's my opponent next but we're still negotiating right now about the rematch with Floyd Mayweather so hoping for that," revealed in a question and answer session with his fans via his Facebook page.
