Persona 5 R- whatever it is- could be coming in March 2019.
With the recent announcement that Joker, the main character of Persona 5, is coming to Super Smash Bros Ultimate, there is speculation that P5R is an enhanced or expanded switch port, or perhaps a new version on all consoles. Whatever it is, we’ll have to see when “2019 3” rolls around. That could be 4 days, that could be march- who knows?
