Will-O-Wisp, I agree with you I don't think Ichigo would win if he gets there, I hope things will go Yhwach way, because I want to know his connection with the Soul Realm. It appears to me there is still a lot more to do and see;

Ichigo reaction to Grimmjow, Arrancars, Ganju with the Fullbringers.

The Bankai's and Shikkais of several characters. (Shunsui, Kisuke, Isshin, Jushiro, Nemu, Nanao, Aizen, Yoruichi, Shinji etc)

The other 3 last Sternritters, plus the meaning of the other letters, (A,B,C,D,L,M,N,U,W,X)

Also, the most important reason, "the last 9 days", because Yhwach is having something big plan for the last day, and its already been 1-2 days past so far, so he has 7 more days at least.
