Seriously. Sony's cool with PC ports of their biggest games (whether years late doesn't matter), but putting their small niche JP games on Switch is too risky or some unfathomable thing?
Aniplex could and should act as the 3rd-party arm of SIE to publish their unwanted JP stuff on Switch where it (IMO inevitably) will find an audience. XSEED also can do the western/NA retail publishing if need be as they've done Sony stuff before (some Wild Arms stuff and Brave Story).
Limited Run actually tweeted last week or so about getting PS1 emulation working on Switch (woah), and asked what folks want to see, naturally I and numerous others asked for Sony's 1st-party lot.
