A new Toriko game is in development for 3DS.
Toriko: Ultimate Survival, due out in Japan in winter 2013, supports four-player co-op multiplayer, has over 10 playable characters (the scan confirms Toriko, Teppei, Rin, and Komatsu), and over 300 types of beasts and plants (like Hannya Panda).
Thanks, Game Jouhou.
