He will become an admiral. That's the spirit of One Piece.
You think he won't? Why?
No, I think he will. You're right it's the spirit of one piece and totally foreshadowed by Oda.
What I meant was that I don't think Coby necessarily has to be able to hold off Luffy like we were talking about in the first 2 pages.
Maybe they meet up a couple of times in the New World and Luffy beats him quite easily but each time Coby is a little closer.
Than in the end of the series, Coby is the main attention in the inevitable change in the WG/marines, as an Admiral.
I just meant that, maybe, they will never fight seriously.
But I could also see that happening, Coby will be damn strong after his speculated training with Garp and Sengoku. I just wanted to throw in another speculation : D.
