Yo-kai Watch 3 has been teased in the latest CoroCoro Comic along with another title in the series, Yo-Kai Watch Busters.
According to translations from Gematsu, Yo-kai Watch 3 will be announced in next month's issue of the magazine, along with more information on Yo-Kai Watch Busters.
The latter started life as a game mode in Yo-Kai Watch 2 and the release will be a single release, standalone title. It allows four players to join up and defeat yo-kai bosses.
Yo-Kai Watch 2: Shinuchi was released for 3DS in Japan last December, and as of February 2015, the Yo-kai Watch series has sold over 6.5 million units in Japan.
Level-5 is heading to E3 this year to reveal the PS4 game its been working on, so hopefully we'll also be graced with good news on the Yo-kai Watch front.
