In the midst of officially announcing Arc-V in the west, Konami revealed on their official Facebook page that they do plan to complete the ZEXAL dub. They intend to provide both dubbed and subbed versions, as well as complete the official sub of 5D’s.
The subs are currently hosted on Hulu (which means no dice for most non-US residents), but they also make reference to an “international streaming solution”.
