You know Toei have been doing stuff like this for years now. It's never going to change at this point, since they pretty much did the same thing with the recent Saint Seiya dub. Like I said before Toei is really strict on their series. It's one of the reasons, why it took forever for Dragon Ball Z Kai: The Final Chapters to come out over here . It was at the point a lot of the Dragon Ball cast members confirmed that they already completed the dub for the series like an year and a half before the episodes even aired on tv and came out on both dvd and bluray.
