ditto to what whiteistari said. as long as I can understand the text I couldn't care less about voice acting. Also, they might as well just keep the Japanese voice acting because don't most people hate dubbed voicing anyway/play with Japanese voicing when given the option? Or they could do something like what Fire Emblem: Awakening did and have American voice actors/actresses record a few words and put them on repeat. Bottom line, I feel like the amount of voice acting should not be an excuse for them not localizing this game.
I hope this one comes out here. It looks like what Final Fantasy used to be with a touch of new school to keep it fresh. I don't know if that's accurate or not, but it's a game I'm really interested in all the same.
