Sakurai made a surprise appearance on a Nico Nico show that talks about video game music and sound effects. The episode centers around Smash Brothers, and Sakurai crashes the party around the 1 hour 15 minute mark. In it, they discuss the music in Smash Brothers, and composers of the game. The guy on the left is Kenji Ito, who composed some songs for Brawl and Sm4sh (Space Armada and a couple of other pieces). Sakurai mentions how the composers can put unique spins on music tracks. For example, Masato Kouda, who worked on the Monster Hunter series made the Vs. Ridley track.
Afterwards, they discuss character selections. Sakurai notes some absurd requests for characters such as Spongebob or Goku. When Tomokazu Sugita (the guy in the middle. He’s the voice actor of Chrom and Takamaru) starts mentioning other absurd characters (Like Segeta Sanshiro), Sakurai says, “There’s always Mii Fighters”.
Then Tomokazu Sugita makes a comment about how happy he was to see Takamaru. Sakurai reveals that Takamaru was briefly considered for a playable character. However, since his popularity was too low, Sakurai felt it was impossible to add him.
In the final part of the video, Sakurai states that Mewtwo is almost finished. He then states that Mewtwo will be released very soon.
