Typical Bleach chapter... But at least one thing has caught my mind: Ywach has the power to create things so, can he create life? This would help giving this a true final battle feeling as right now the sides are like 20+ vs 7.
But if we think about it, Ywach has Zanka no Tachi. I guess he will just rise an undead army and put everyone to fight and when we remember that in some sense everyone is part Ywach then we can say that anyone that died in this arc has a chance to appear again right? And of course, this way we'll see Yamamoto vs Shunshui and that will be epic.
