If they were really trying to move on from 🍅Yuimetal 💀 they wouldn't be rehashing and using old material they remove 🍅💀 symbol from the band logo but apparently they're not committed enough to go the whole way
They used the shin version prior to the full version including Momometal in the second show. The Tribute to Yui in karate is touching the concerts and TOO album is a bridge between what was and what's to come in the full new album. As for the logo it has been pretty standard through out there life, only difference was very early logo had a lightning bolt for Su not wings. They have now dropped the wings Su, the hearts Moa and the little Skull for Yui leaving a clean logo. They have moved on the only ones that haven't are Yui Stan's, and they not going to stop performing older Material just because Yui left.
they simply made minor changes and experimented with new pieces and arrangements. and of course that version is only available at babymetal solo concerts in Japan only. but i really like it. I really like every musical change from babymetal over the years.
