What if U7 has to win the tournament now?

[Kishido]

I know Zeno and Goku are buddies... But Goku and Co have broken a strict rule of time traveling.

Zeno may wipe out Zamasu but if he wants to wipe out U7 as well? And only the word of Goku to not to do so if they win the tournament?

[Yedis]

I don't like this stipulation because we know Goku and Co would just win it, it's not like they would kill off all the characters.

I predict this is what will happen in episode 67.

Zen-O (to Trunks): "You broke the Time Travel taboo several times, you see. You deserve death, you see."
Trunks: "What?!?"
Zen-O: "However, you see, since you helped stop Zamasu, you see, I will let you live."
Trunks: "Really?"
Zen-O: "But only if you come with me and be a member of the Time Patrol of the Supreme Kai of Time for the rest of your life. You see?"
Trunks: "..."
Zen-O: "I will let you say your goodbyes, you see."
