I really doubt it at this point, Oda LOVES never giving us what we want and need.
Still waiting on Akainu vs Kuzan/Aokiji, The Payback War, Rocky Port Incident, Gods Valley in full, Shanks vs Kaido, Green Bull vs Weevil (where was Marco during this too?) and whatever else I might have forgotten atm.
I would say Moria vs Kaido too but that was a background panel after over a decade of waiting to see it....The anime barely extended it too, so yeah....
Don't get your hopes up too high. Oda is far more likely to disappoint us than give us what we want. I would love to see Mihawk vs Shanks as one of the things we've yet to see in One Piece but the more I see to want to see something happen in OP, the less likely it seems to happen, aside from things like Wano and Elbaf arcs actually happening. But currently my record is overwhelmingly negative luck or w/e lol..
Oda hates drawing fights and doesn't want to draw one more than 1 chapter long. Unless he draws it so he can glaze Shanks the most "underrated" character in the series clearly, he will give us nothing more than breadcrumbs at best.
I wonder what he thinks of these fanmade chapters of stuff like Shanks vs Mihawk, I wonder if it winds him up ironically? Or he thinks he doesn't have to draw them now too, since his fans will do it for him? And thus the same for fans who make animations of things we have yet and most likely will never see too?
But you know, Oda will gladly wasted tons of chapters on irrelevant shit, annoying characters, reactionary panels, goon moments, literal filler for multiple chapters etc than give us what we actually want and need.
