No but he said after the time skip that he was only halfway done. And i believe the timeskip was like 2-3 years ago, and then op was about 10 years old. So based on what he said, we still have 7-8 more years of op.Didn't Oda say that One Piece will go for another 10 years?
To the OP
NOO oda is not ANYWHERE CLOSE to ending it. If he were to end it abruptly then it would be ove in a minimum of like 3-5 more arcs.
