Version officielle de pourquoi il y a une pause cette semaine:
"The official One Piece website has come out with a post to explain the absence of One Piece in next week’s issue of Weekly Shônen Jump.
According to the website, One Piece will be absent from Weekly Shônen Jump Issue #2, officially on sale Monday, December 8th because the author Eiichirô Oda is conducting research and/or collecting information. The post also mentions that due to an oversight, chapter 769 didn’t include an announcement of next week’s break and the magazine apologizes to its readers for any possible trouble and/or concern this unannounced break might have caused."
