so apparently the West release is Xbox One/PC exclusive only:
"Xbox boss Phil Spencer made a huge deal about PSO2's launch being only Xbox One-exclusive on consoles"

and not only that, nothing Sony related has been anywhere in sight to indicate it coming to PS4. If I had to guess at best for Sony fans its a timed exclusive but even if you wanted to play, make a JP PSN account but naturally expect no translations. Sony fans have a PC version to play too if they want to that bad or just throw a fit and not play it all since it is already on the PS4/Vita and Switch
