Character specific toggle, too
When BlazBlue: Cross Tag Battle releases in May, it will contain an English dub for fans of not reading subtitles. While this may seem like a no brainer, every BlazBlue title past Chronophantasma has axed dubs in favor of cutting costs for localization. I’m guessing the inclusion of characters from RWBY spurred Arc System Works into preparing an English voice-over for the rest of the cast to keep consistency.
If that wasn’t enough, you can even toggle the voice acting between Japanese and English on a per-character basis. This was shown during a live stream event where two members from Arc System Works confirmed that dub will be in while playing with characters from RWBY using both English and Japanese options. You can see that clip here.
