According to multiple sources, Persona 4: Gold Edition may land on PS4 and Switch next year.
The first is the revelation of the well-known industry insider Zippo, who has revealed that "Persona 3: Pocket Edition" will be remade (unconfirmed), and "Persona 4: AU" will be remade (confirmed). Recently, he posted on his blog that "Persona 4: Gold Edition" will land on PS4 and Switch in 2022, and Zippo also said that three of the seven projects for the 25th anniversary of "Persona" have only been announced, and there are four that have not been announced, and there will be more surprises next year.
Another tip came from Twitter user Faz, who found that adding /v2 to the URL of Persona 4:AU would show a PS4 and Switch version of the "Midnight Channel Collection", which was a combination of Persona 4:AU and Persona 4: Gold Edition, while the previous /v2 page would not show this page.
For now, the next new news from the Persona series is expected to be released in February 2022, when we can learn more.
