"Basically, it will be fully voiced. We still haven't decided the voices of the characters that weren't in Final Fantasy 7: Advent Children," said Nomura when asked about the voice-acting teased in the game's most recent trailer.
When asked if this meant the dating portions would be fully voiced, producer Yoshinori Kitase replied "It would be impossible not to. However, since it's different from that time and social situation, we need implement the reproduction of original events carefully."
Asked about the game's map, Kitase said, "We can't say anything yet, but we don't plan on fussing about whether it's a so-called open-world or sandbox. But since Nomura is more focused on the creation of the scenery, we want to express an environment character actions affect the scenery."
So now the question is whether we'll have the option for Japanese voice-acting with English subtitles. Kitase said, "We're at the stage where we can say we're finally getting started," so it sounds like we won't get a lot of details for a while yet.
