For me, Neko's announcment just fell flat. It wasn't as epic as any of the prior ones. And it came from somebody who a) wasn't already an announcer in the arc (Like Gyatz in Dressrosa, who was constantly announcing), or b) a walking reaction face who watched the whole fight (Brullee).
He was just randomly inserted to be the voice of the announcment.
However I'm not denying the words he said. Kaido si down 100%.
