Ok so they come back and what? Oda already had a chance in wano to focus on both of them extensively and he didn’t. They get a small cover story are a few panels here and there for fan service at best.
I find these comments a bit contradictory to his recent statements about wanting to draw a hype ending to the story, but I guess we all have different interpretations of what is hype.
Oda has the right to do whatever he wants with his manga even if I personally find it a bit disappointing.
