ONE PIECE, When do you think it will end?

Eiichiro Oda and his team have given a rough time frame of 5-7 more years. And also said it might change depending on the future.
To be honest, I find One Piece to quite good to keep watching as long as possible. But Dragon Ball needs to stop. I loved all of the Dragon Ball sagas including GT, I know sorry to hurt your feelings not everyone like GT. I like GT because it is Dragon Ball. But now it is no use to squeeze out more from Dragon Ball. The story is getting quite out of hand.
