It's possible there could be a reprint since Persona 3 sold extremely well for what it was... enough for Atlus to bring over Persona 3: FES, as well.
This might be Atlus trying to strike while the iron is hot and everyone is already excited over one Persona, surprise, here is Nocturne, get more of your SMT fix. It makes sense, when you think about it.
I guess we will know if Amazon suddenly gets new copies in stock, since Atlus goes directly through them now.
It seems too much of a coincidence that Play-Asia gets new copies at the same time as some random Ebay seller does, and decides to sell them lower than everyone else.
