Too much confusion from this show.
Console Exclusive implies there's a PC version.
Console Debut implies possibility of release on other platforms.
Yakuza 0 has been out in Japan since February for PlayStation 4 and PS3. The slide called it a "PS4 Console Exclusive." Sega's press release mentioned nothing about a PC version.
Gio Corsi called Nioh "exclusive to our platform." The
announcement trailer for Japan at SCEJA Press Conference 2015 said "2016 - Only on PlayStation 4." The
YouTube description for the new trailer released at PlayStation Experience says: "Nioh is a dark, samurai-centric, action RPG currently in development by Koei Tecmo Games exclusively for the PlayStation 4 platform." The slide said "PlayStation 4 Console Exclusive."
Both Gio Corsi and the slide called The King of Fighters XIV a "console exclusive," but the
latest press release (released today) is headlined with "PlayStation 4 Exclusive The King of Fighters XIV."
The slide called Ace Combat 7 a "PS VR Exclusive." The press release indicates it's a PlayStation 4 game with support for PlayStation VR.
Adam Boyes called Ni no Kuni an "exclusive PlayStation 4 title" and the
PlayStation Twitter account also called it an "exclusive" title. The slide said "PS4 Console Debut."
Anyway, whatever the case may be, these are all coming to PlayStation 4, and if you like most of these, there's a chance you enjoy Japanese video games, and there's a shit ton more coming to PlayStation 4, so be happy.
