Do you think the new transformation of vegeta will be important again?

[Shorty GZ2]

Considering the newest chapter featured Gas pointedly asking Bardock if he fights because he jives with Vegeta's main hangup this arc of "atoning for the sins of all Saiyans" (to which Bardock says "nope") and Bardock growing stronger/getting a zenkai/power boost from the pure Saiyan instinct to win a fight, plus Vegeta's first sentence upon transforming into Ultra Ego that he reiterates throughout his fights being that "(A God of Destruction taught me that) power derived solely from instinct is unbounded," I'd hazard a guess UE will still be relevant later on.

It's not gonna be in Super Hero though. In the future outside of the manga, who knows. Vegeta eventually did transform into SSG in Broly (even when he didn't really need to by that point) years after he'd already transformed into it in the manga by Toyotaro, overseen by Toriyama.
