In his statement, he considers retiring but it's not final yet, so as long as there's no formal announcement from him about retiring, then we can assume that we will still see him fight again.
But after that then a fight of him came. It is true that these hints will remain as it is until he finally says and gives an official statement for his retirement.
As Pacquiao said, he had done enough already for boxing, and boxing had done a lot for him. So yeah, he should retire while he can still enjoy the fruits of his sacrifices. Don't wait to suffer major body damage. He's not getting young. Time to give the ring to younger generation. His record is already astonishing and can be lined up to boxing greats like Muhammad Ali and Sugar Ray Robinson.
