Technically the news from Anime Expo 2016 is simply that the games are coming to 'other platforms', but I'm going to make the risky decision to say that this means they'll be coming to PC. Just last week 'decision game' Zero Escape: Zero Time Dilemma launched on PC alongside its 3DS release, and now this week comes news that its two predecessors 999: Nine Persons, Nine Hours, Nine Doors and Zero Escape: Virtue's Last Reward are both being ported to PC.
I suppose it seems inevitable in retrospect.
