FYI, Disc 3 of Budokan has the full ceremony, which is around 20 minutes.
The girls who get to stay in their own teams were really glad. You could see the relief, especially in Yuko, Acchan, Mariko and Sae.
Some of them took the change pretty good imo. Kasai kept herself together, as well as some of the under appreciated Team B girls, who probably see this as a chance.
I also noticed that new Team K got most of the girls who really not happy; Moeno, Itano, Miichan, Tanamin and Fujie, to name a couple. I hope that there won't be a division between the core of team K (Sayaka/Sae/Yuko/Erena) and the new girls.
I just want to say for one last time that this was truly heart-breaking to watch and that they should not have done it like this. I do think that they changes itself will be interesting and beneficial for AKB48 as a whole.
