One Piece creator Eiichirô Oda has made a comment in Issue 8 (January 20, 2014) of the Japanese Weekly Shônen Jump about the previous edition of Jump Festa saying:



Jump Festa’s [Super] Stage is really fun every year, but have decided for the sake of my aesthetics as a Mangaka, that this year’s appearance would be my last. Thank you.

Be assured however that this statement does NOT mean that One Piece will end this year, only that Eiichirô Oda has — apparently — decided out of personal beliefs as a Mangaka to not do anymore public appearances again from now on. Whatever the reason might be behind this decision, let’s all respect it.
