The new announcer added with the Braver patch isn't very good frankly. Especially in contrast to Tetsuya Kakihara as the announcer in PSO2. People seemed to like Otika's broken English in the NGS trailer he voiced over and coincidentally he also did the announcer for a King of Fighters game (KoF being a franchise beloved for its broken English in older games (R.U.O.K.? BUSTA WUFF! I STRAIN MY HANDS... WITH YUR BRUH! PREDICTABO!)) so he has experience for the role besides the Decadriver.
Honestly when I heard his voice in the trailer I thought for sure was going to be him to begin with because of how cutrually important Kamen Rider is in Japan and we already had Tetsuya Kakihara who voiced Simon in Gurren Lagann ( along with a bunch of other anime and game roles) in PSO2.
