Honestly I'm kinda starting to believe on the 5 years shit considering how much Oda and his editors has been saying this for multiple times...
And let's be real for one sec, Elbaf is NOT getting skipped that's for sure. So Elbaf will most likely be a short ass Arc that's long as Zou or maybe even shorter
But then yet again after Wano there'll be a whole lotta shit happening like maybe Luffy will hear about Sabo, Vivi and Hancock in danger and go to rescue them and Raftel will be the final arc or could be the opposite.
