Alright, I'm gonna try and predict the future here.
-Most people seem to agree that, most likely, One Piece will end after 1200-1400 chapters
-Fact: One Piece's biggest inspiration is Dragon Ball. Oda agreed don't bother him about it
-Namek lasted 87 chapters. If it ended there (like Toriyama wanted), Namek would've made up 26% of Dragon Ball chapters
-Toriyama made it so long intentionally, he wanted DB to have an epic ending
-Estimating 1300 chapters of One Piece with Raftel taking up 26% of the overall content, Raftel will last 339 chapters. That's about 7 years on Raftel.

tl;dr: Raftel will be the new Namek.
