You know what? I think that the dubbing of the numbered FFs has been very good so far. I can forgive the weirdiness from FFX's because it was the first one and there where a lot of techniques to be learn regarding dubbing videogames into English. But even so, the dub from FFXII and FFXIII were very good, specially FFXII --even FFXIV had some acceptable voice acting every time the characters talked using their voice and not text boxes. However, I think I'm playing FFXV in Japanese. I don't know what happened, but the voices used on this trailer sounded plain, emotionless and soulless. It may be because it was just the direct dubbing of a trailer and not the voice acting used in the final game, but even taking that into question, I'm not very confident in this dubbing process at this time.
Please, Square Enix, learn from the acceptance the Japanese voice acting had in LR:FFXIII on PS3 and the two FFXIII games released on Steam, and give us Japanese voice acting on all platforms >_< (In fact, I think it was confirmed that Type-0 and FFXV came with Japanese audio as well. I'm grateful for that).
Edit: Grammar. Remember that I'm not a native English speaker. A lot of mistakes are to be expected
