Let’s put it on record that this is in no way confirmed and is just a rumor. But according to the Spanish voice actor of Bills from Dragon Ball Z Battle of Gods, there will be a new Dragon Ball Z series. It is said that the story line would revolve around the other Gods of Destruction from the other universes. Check out a picture of where this is featured below. And again this comes from Club Manganime which I believe is a fan publication so only take this as a rumor.
