@Kaptayn:
So… is this admitting that Greg literally spoils stuff, purposely ? And then, they just add fake predictions so that we never know what will come out true or not ?
It's not spoilers without confirmation, but when you're using actual facts and story bits, and decades of familiarity with how the author works, and are as obsessed as Greg, you hit close to the mark a lot of times. There's been at least a couple occasions where something that was an educated guess that has been rejected for being an outright spoiler for something that wouldn't actually come up for a couple years, such as Kaidou terrorizing Wano, or the likelihood of him being a dragon. (Greg's column skirted around that issue by saying "OIda likes strong beasts and I don't think Kaidou is a Lion, what else could he be…?)
Like, he correctly guessed that Brook might someday sing a song about Nekomamushi based on the VA having a song about that already, and lo, the very next week that appeared in the manga, and that was without Greg getting any advance insight at all but just knowing how Oda rolls.
Ironically, its Greg himself that gets spoiled when a random theory gets turned down for this exact reason.
So yeah, some things are just "wacky crazy guesses" that Greg doesn't really fully believe that are more "the over-active imagination of crazy fan!" in order to mix it up some, because yeah, if he was right even 90% of the time about future stuff it really would turn into spoiler corner.
