We're talking about official pre-release information though, rather than a vague ambiguous mystery which is told from an in-game perspective (and also over 20 years old). It's not outside the realm of possibility but I'd be willing to bet that there's no Elite 4 anymore.Alright, but just remember...
(... Or, you would have been...)
EDIT: On another topic, what does that say in English Kanburi? Google translate mostly gives gibberish and I believe you can read Japanese?
E2: Nevermind I just realised its the probable SirFetch thing, should be an interesting reveal, I hope they do more of this interactive style of marketing in future, it was pretty fun to discuss it with other people.
