Premise: Some God of Destruction awakens from a long sleep, discovers someone has defeated Freeza, and decides the universe needs balance (which I guess Freeza was providing by being a dick?) and challenges Goku. Despite the participation of Akira Toriyama himself in the development of this new movie, the same DBZ formula is likely to follow.
I wonder how Kaio got a new planet. The Kaioshins, perhaps?
