Like 90% sure the 1045 shit is
@SDfear trolling lol
The 1034 stuff does seem to maybe be legit but it was that same poster who claimed stuff up to 1045 was possibly leaked (which is why I think we got the troll post after lol).
But tbh, we already know how Oda's manga process works. He does not have outlines written that far in advance or has never alluded to it being that far in advance. The most we know is he is 3-4 chapters ahead at any given time, that's it. It was definitely a ZKK wish fulfillment/troll post to align with the 1045 claims from that user.
