"Atlus announced today that Persona 5 Royal will be released

Also from Gamespot
"Persona 5 Royal
launches exclusively for PlayStation 4 on March 31, 2020 in North America and Europe--the game has been out since October 31 in Japan. We've been following the game since it was announced in Japan, and you can check out our P5R reveal trailer analysis or our breakdown of the several new features in the game."
