There were rumors going around that Atlus was going to announce a new Persona dancing game like Persona 4: Dancing All Night since the website "persona-dance.jp" had been discovered and they did just that. Atlus announced not one, but TWO new Persona dancing games that will hit Japan next year with Persona 3: Dancing Moon Night and Persona 5: Dancing Star Night.
Persona Q, Persona 4: Arena and Persona 4: Dancing all Night were all canon games in the Persona timeline so I would assume that these are as well. I won't get into the spoiler territory here but let's just say that I am intrigued by the Persona 3 dancing game the most since this trailer has HUGE implications if it is indeed canon. Those who played through Persona 3 will know exactly what I am talking about.
Persona 3: Dancing Moon Night and Persona 5: Dancing Star Night hit the PS4 and PS Vita in Spring of 2018 in Japan. No word yet on an international release date.
