Whatever they decide to do with this moment, I honestly think doing this would be the worst-case scenario. It undermines the impact of the scene so much for me.  

Once it's fixed, sure, go ahead and show off Ichigo's new Bankai, but this moment, with his brand new Bankai snapped in two instantly, right after his triumphant speech about overcoming despair, is peak Bleach. 

It's such a perfect encapsulation of Yhwach as a character, themes, and tone that I genuinely can't understand why some fans want to see it changed. 

This moment really highlights Ichigo's core struggle against fate and how it connects to Yhwach. Fate is this oppressive, grinding force, and Ichigo's wish for strength, to shatter fate, is a perfect reflection of his defiance of it. 

To me, Yhwach, with his power to control and rewrite the future, embodies the ultimate version of fate's control, while Ichigo has always fought to break free from those chains placed on him, and his new Bankai, his greatest weapon, is dismantled before he can even comprehend what's going on.

This isn't supposed to be an epic, triumphant moment for Ichigo. Sorry, but that's just not the aim of the scene. Want to see Ichigo's new Bankai in action? That's completely fair, but this isn't the right moment for it. 

The true final fight is the place for it to shine. This scene, as it stands, is too great to lose its meaning by forcing a flashy showcase here.

Idk, just my thoughts on it. I have a feeling they'll change this, which to me is a real shame.
