There are probably 10 big franchises that keep Japanese gamers interested in PS, which includes FF, DQ, KH, Yakuza, Resi, MoHun, Persona, Tales, Souls games, NieR.
FF16 may not appeal atheistically to Japanese gamers in the same way that 13, 15 and 7R did. There's also been radio silence since the reveal.
DQ12 is a ways away.
KH4 MIA.
Yakuza Like a dragon, available on PS4. Next Yakuza a ways off.
RE8 available on PS4 and next entry a ways away.
Persona 6 MIA.
Tales, available on PS4.
Souls games, available on PS4.
NieR sequel. MIA.
MoHun, moved over to Nintendo.
Feels like Japan has been looking for a reason to move away from Playstation since the PS3 and now they have one. Little or no incentive to buy a PS5 at present. PS4 managed to sell 10mil units and PS5 won't come close to that.
