As part of the Xbox + Bethesda Games Showcase 2022, it was announced that Persona 3 Portable, Persona 4 Golden, and Persona 5 Royal will be coming to Xbox and PC consoles. Switch users who wanted to play Persona 5 Royal as much as anyone else were left out. So far, Atlus has not made any announcements or even hints that the game may appear on the console from Nintendo.
A page with a physical edition of the game for Nintendo Switch was found on the website of one of the Swiss stores. There is a high degree of probability that this position appeared by mistake, or even is a joke of one of the employees.
However, hypothetically, Nintendo’s console should be able to handle Persona 5 Royal. Some fans are hoping that there will be an official announcement at the next Nintendo Direct and the last three games in the Persona series will be released on Switch.
