As for the North American version of One Piece manga volume 71, well, the release date has not yet been announced by Viz Media. We expect it will take some time for us to get it; probably a few months to a year for the hard copy version. One Piece manga volume 67 was just released last month on June 4th. The North American release date for One Piece manga volume 68 is currently September 3rd while volume 69 is scheduled for December 3rd, and volume 70 for March 4.
