Look, we could roughly tell that the strawhats' position would be on Sabaody Archipelago near the Red Line - second half of the One Piece World. And this is 400 episodes in anime after they travelled from Laboon (the whale) down at Sabaody. They'd travel another half. So I expect another 400 episodes.. or more since One Piece usually has longer arcs for stronger enemies.
