Wait really...? Can you break this down a bit with a Japanese Version of the Interview? Or do you know an English source that is accurate?
Translation: “Hi I’m Oda, Are you enjoying Jump Festa? I’m watching OP Super Stage with you. Its fun, indeed. Actually, I visit Jump Festa every year to have dinner with Strawhat’s VA after Jump Festa.
By the way, One Piece will finally enter Wano Arc next year!! (cheers!!) Some well-informed audience might think, “You said the same thing last year, right?” Yes, I did say that because I thought OP would be able to enter Wano in 2017. This time, I’d like to add new information.
I’ll introduce one of the legends that lurks in the One Piece world. The greatest enemy ever for the Strawhats will hinder them on their journey. Perhaps it will be something related to Whitebeard. Oops, it seems I’m being too talkative.
Can you believe Marineford Summit War will look “cute” compared to that?
Anyway, there are tons of stuff that I wanna draw next year as well. I’ll keep moving forward with my full force! I’m sure you’re gonna love it!
-Eiichiro Oda”
from yonkou on tumblr. he said he was adding new information because he said the same thing about Wano last year, then said he's going to introduce a character who might be related to whitebeard who will be the straw hats greatest enemy, making marineford look cute. its after he said something about wano but it isnt actually about wano.
