The old chant gave an instant impression that something.' Japanese like' was going on. FFG control the game so have the 'right' to remove the chant but I doubt the new chant will catch on so I suspect silence or a weak response or the odd person shouting banzai.
If they had to change the chant then why not UTZ HANTEI - bears similarities in sound so the odd person shouting BANZAI would get drowned out. Saying that there would be problems when another Imperial Line took over...
As an aside the SS motto was 'my honour is called Loyalty' so doesn't bear much resemblence to the new chant beyond massed shouts in german of honour so anyone attempting that connection is making a slight jump.
