Well, better not ignore the actual blog here. The truth about Oda's hiatus... he's actually been part of a writing duo. His partner George B. Sanji would help him come up with the story while Oda took the credit. The character Sanji is actually based on the real life Sanji, like a self-insert character. Oda would always draw the fictional Sanji with the wrong eye showing, and G.B. Sanji would have to correct it. After the chapter 3D2Y, Oda and Sanji got in an argument that resulted in Sanji leaving the team to move to New York and work on his own series: SanTron (coming 2017). Oda had a hard time keeping up with one chapter a week once he started drawing every page himself.

This is when the timeskip happened. Oda mistakenly drew Sanji the character with the wrong eye showing, so he just pretended like it was on purpose and started drawing it like that all the time. He also had a hard time capturing Sanji's personality, turning him into a one-note nosebleed machine. Remember how Sanji use to cook? G.B. Sanji got so fed up with his portrayal in the manga that he emailed Oda and asked him to write Sanji out of the series. Even now, Oda has to take extra time to draw the chapters now that his best friend and partner left the series.
