'Dragon Ball Super' episode 56 may see the transformation of Black Goku into Super Saiyan Rose

"Dragon Ball Super" is already in its 56th episode, and it's titled "Black Goku Rematch! Super Saiyan Rose Appears!" The episode is only a week away, but fans are wondering if Super Saiyan Rose is actually Black Goku or Son Goku himself.
The initial guess of the fans is that Black Goku will be transforming into the pink Super Saiyan. However, there are other viewers who are actually thinking that Super Saiyan Rose will be achieved by Goku to defeat Black Goku. But then again, Super Saiyan Rose could be a totally different person by the time he (or she) shows up in the episode.
A trailer has been released for the next episode of "Dragon Ball Super" and, though the clip is short, the next episode will also see Black Goku going up against a Blue Super Saiyan Vegeta. Knowing Vegeta and his ongoing rivalry with Goku (Kakarot), Black Goku will most likely let Vegeta go all out without the guilt of seriously hurting one of his friends.
Meanwhile, an extended look from Fuji TV also shows Trunks on the lookout for Mai. He finds Mai's capsule with her body missing from it, but seeing as they were together in more clips from the trailer, Trunks will most likely find her, or it could be some sort of flashback. That's up for the showrunners to decide.
The translation of the episode 56 summary also reads: "The repairs on the time machine are finished, so Goku, Vegeta and Future Trunks head to the future. In a ruined future city, the three meet up with the resistance, and run into somebody unexpected."
The next episode of "Dragon Ball Super" is set to premiere on Aug. 28 on Fuji TV.
