The game won't continue the Hope's Peak Academy plotline tho, it'll be a complete new story. I think there's enough difference between the names Danganronpa 3 and New Danganronpa V3.
That could be the case. The console still sold enough for that price outside of Japan, so they might even not change it. Wouldn't be a nice move, but who knows.
I think the lower price is a incentive for people in Japan to make the jump from PS3 to PS4.
Persona 4 Arena Ultimax: 2 months difference.
Persona Q: simultaneously
Persona 4 Dancing: might also be at the same time, though it's brought to Europe by NISA for whatever reason.
EDIT: Forgot Devil Survivor 2, that's getting half a year of delay. :unsure: Why can't they keep their shit...
