or maybe it's a plot twist that it takes place in 2011 alongside P4
This is 100% sarcasm
I don't think that's going to happen, but I don't think that's an absurd thought at all (it's one I had thought about, as well). I don't see them regressing when it comes to the dates the Persona games are set inespecially considering the themes that Hashino wants to tackle are deliberately made to be "with the times"but I could also see a scenario where P Studio goes "screw it" and rids themselves of any shackles related to something like that. A main Persona game set in the past or whatever (though, again, I don't expect that because "modern Japan" is pretty much a core part of the franchise).
