Exactly. I'm just putting it out there that:
- She has been waiting for Luffy and Luffy only.
- She has history with Ace
- She has directly asked Luffy to leave Wano
- She has openly denied her father's wishes of ruling "New Onigashima", all the while 2 Kozuki heirs are STILL ALIVE (this one kills me the most).
This points to a likelyhood of her joining, but on top of this, we still know next to nothing about her character.
So all I've been saying, on repeat, is to just wait!
