Domain registration had almost spoiled, but now we have the official: Person 5 R exists and has been announced with a teaser trailer da Atlus same.
At the moment there is no information and these are all postponed until March 2019: the only thing we can notice is the PlayStation 4 logo which can be seen at the beginning of the video, which suggests that the game could be a Sony exclusive.
Doubts apart about what this title could be - some speculate a racing game given the R, others a final version even though it already exists - the real disappointment is for Nintendo Switch users, that after the introduction of the Joker in Super Smash Bros. Ultimate and the different rumors that they wanted Persona 5 to land on the Japanese hybrid, they saw their console excluded.
Actually, however, there is another registered domain that corresponds to "Person 5 S ", and it is the latter that could refer to the Nintendo Switch version.
At the moment it is all we know, we will know the truth only to March 2019, when Atlus will reveal to the world what this really is Person 5 R.
