Heck my hope for this series is high because Battle of Gods was fantastic, the storyline for Dragonball: Xenoverse was great and I loved the new characters introduced and I'm hearing good things about Revival of Frieza.
So they have established that whomever is taking care of Dragonball at this point in time is doing a fine job with it. So hopefully the streak continues and we get a fantastic new series.
Oh right but I understrod that they've destroyed them all one after another and stopped short of destroying Goku's. I didn't get from that that these 12 universes co-exist at the same time.
No, Beerus is the God of Destruction in THIS universe. Not any others. He tells Goku that Goku is the 2nd strongest person he has ever fought, 1st being Whis, and then goes onto mention that there are other even stronger warriors then even him in other universes, stating that there are 12 other universes. Going off the top of my head here, so not direct quotes.
