Along with the matchups that we know about (like Goku battling the fused female Saiyans of Universe 6!), there are also a lot of teases and spoilers that hint at some new power ups also coming soon:
Per the Heroes livestream, Goku will power up Ultra Instinct soon ("Omen" is the key word), and Vegeta's not gotten serious yet either.— Odd Blankenship (@Herms98) October 22, 2017
This tease from from the Heroes Livestream (via Odd Blankenship) seems to indicate that Vegeta is going to have a big battle or powerup in the coming rounds of the tournament. Needless to say, fans are already buzzing about whether that means Vegeta will max out his SSB form, or perhaps keep pace with his rival, Goku, by unlocking some new kind of power. We've already seen artwork of what Vegeta could look like using Ultra Instinct, and it's something that many fans are excited to see!
Meanwhile, you see mention in the Odd Blankenship's breakdown that Goku still has to master his new Ultra Instinct state; Jiren may still have a final form to reveal as well; and the upcoming fusing of Caulifla and Kale will create the first female fusing in Dragon Ball history.
In other words: you better stay tuned!
