Has it been confirmed whether Nintendo or Square-Enix publishes these titles outside of Japan?
They didn't say anything, but back the when SE published VIII, IV and V, they dropped the number from European release. After Nintendo picked up publishing duties, the number stayed even in Europe.
I also wonder whether they let Nintendo to translate the games, or will they use their original english scripts. I know VII was never released outside of Japan on mobile, but VIII was. If Nintendo hadles translating, this release could stay Nintendo hardware for a while.
