Persona 6 would have been internally postponed, according to a leaker who was considered trustworthy for previously disclosed information. It will be impossible to release in 2023 for the next chapter in the Atlus series.
This is totally unofficial information, whose validity is tense, but which is nevertheless taken into account due to previously spot-on leaks from the same source.
The message I'm A Hero Too on ResetEra regarding Persona 6
The comments from the ResetEra forum were made by a user named "Im A Hero Too," who had beforehand known about the Persona 3 Portable remaster.
The user in question stated that "There is absolutely no possibility that Persona 6 will be released this year," adding that "there is a new release date that is still unknown but which I will not disclose."
According to the leaker, this decision "May have been made first to release the remake or the other game in development first", adding that "if the teaser were to be present at the next Sony conference, I should be able to know in advance and in case I will confirm it".
When it comes to "internal," things are always very vague, because such information is often difficult to find. In any event, we await any developments from Atlus and Sega. We know that Atlus will release several unreleased titles in 2023, among which might also be Persona 6.
