What are the chances of NISA doing more physical releases on the console?
not very likely, but i wouldn't rule anything out. if we're talking 2018. they started winding down a bit this year with digital touhou games. if they didn't have direct followups to games that were big on vita (demon gaze, danganronpa, ys, yomawari), it would probably have been unlikely after summer. i'm sure like a lot of niche publishers, they really want people to move to newer platforms (and ps4 isn't even 'new' anymore).
