After the premiere of Persona 5 animation OVA Dark Sun, Persona 5 R was officially announced after the animated episode. It wasn’t announced as a nintendo switch exclusive. Instead, we saw a PlayStation logo at the beginning of the trailer. That doesn’t necessarily mean it’s a PlayStation 4 exclusive but we’ll find out more in March 2019.
Persona insider, MysticDistance was right about the existence of the game and he was also right about the announcement coming after the animation. But the game isn’t exclusive to switch.
It’s possible to see a Switch announcement for Persona 5 R at the next Nintendo Direct. No other information was given and we don’t have a release date as of yet. In the meantime, fans can still enjoy Persona 5 on PS3 and PS4.
