It was discovered yesterday that the Atlus registered domain for a Persona Q sequel had been updated, with its nameservers being moved to Atlus ones instead of the default Onamae ones.
Today, on July 28, 2017, the same happened to the previously registered domain “PERSONA-DANCE.JP,” hinting at a potential sequel to the dancing game spin-off Persona 4: Dancing All Night, originally released for the PS Vita in 2015.
