'Dragon Ball Super' episodes 60, 61 spoilers: Black Goku is the real deal; Vegeta to reach Super Saiyan White form?

The Japanese anime series "Dragon Ball Super" has just delivered on its promise to reveal the mystery behind Black Goku in its 60th episode. The revelation came as a shock to Son Goku himself, and it will be interesting to see how this would affect the Saiyan's motivation to fight if it meant he would have to damage his own body.
As it turned out, Black Goku's body was indeed the real Goku's body, except that his heart was Zamasu's. What Zamasu wished for when he gathered the Super Dragon Balls was not to create a fake Goku to become his ally, but for him to switch bodies with the real Goku. This should explain why Black Goku and Zamasu had the same ki. As to what happened to the Zamasu whose body the real Goku had switched into, Black Goku sneered and said, "I killed him."
Another intense battle is building up between the Saiyans and the future Earth's adversaries as the next episode of "Dragon Ball Super" promises to raise the stakes even higher.
Titled, "Zamasu's Ambition. The Terror of the 'Zero Humans Plan' Spoken," episode 61 will divulge the details of Zamasu's plans to annihilate the human race. It will also feature Black Goku and the other Zamasu — who may have come from a different timeline, according to fan speculations — combining their powers against Goku, Vegeta and Trunks.
Fans have also theorized that Vegeta may eventually turn into Super Saiyan White, presumably after Black Goku kills Bulma. In episode 60, Vegeta's feisty wife had insisted on coming to the future with them to see if Beerus vanquishing Zamasu in their timeline had indeed made the Future Trunks' timeline a safer place. However, nothing changed, apparently, because the world that Future Trunks' knew moved in an entirely separate timeline from Goku's.
Will the upcoming battle really put Bulma's life in danger? Will Vegeta's Super Saiyan White Form be enough to defeat the combined evil forces of Black Goku and Zamasu?
"Dragon Ball Super" episode 61 will air on Sunday, Oct. 9, at 9 a.m. Japan Time on Fuji TV.
