Questions & Mysteries to what extent is oda gonna change the one piece?

#1
Given that he knows that we know what it is or at least what it will make since long ago ie, creating a "one pièce" of sea, by the help of the ancient weapons.
And given the fact that knowing oda, he would rather give a worse explanation to it just for deceiving the fanbase in their théories as he usually do.

He might already changed his mind several time from his initial plan I guess. We know the older we get the more realistic we are and less dreamy. I hope he keep his young spirit alive at least for this manga.
