During the special stream of "Monthly Famitsu feat.", a new game was revealed by The Pokémon Company president, Tsunekazu Ishihara. This game is Pokkén Tournament and is in development by Bandai Namco with producers from both Tekken and Soul Calibur series.
It is an arcade game coming out in 2015
In answering questions, it was implied that there may be non-arcade release later since it is said to come first in arcades (so a possible Wii U and/or 3DS release)
