With the recent appearance of SSJ4 in the new anime (yeah I know it was in the game the anime is based off years ago), I won’t be surprised if Toriyama brings this form back and makes it canon somehow.
I always fukked with the design, and like dudes said already, it just feels like a true transformation after SSJ3. Not talking about how it was achieved, but it’s overall look. Even tho technically SSJ3 might not be a true transformation either (didn’t Toriyama go back and say it was a mutated version of a super saiyan form
? I even remember him touching on how SSJ wasn’t the complete SSJ transformation and that SSJ2 really was. Honestly dude was just throwing a lot of shyt out there lol.
But I t would be dope if he brought back SSJ4 (or something like it) and made it the true next transformation instead of SSJGSS. I always felt like it wasn’t a real Saiyan form and that other races also had the ability to achieve the power of a god (like Toppo in a way). Toriyama won’t do this, but Broly possibly being the legendary SS that was brought back by the wish could also be the one to transform into this new form (SSJ4 or not).
I also feel like this canon Broly is gonna be a huge upgrade character-wise. I’m tired of the OG Broly as well and looking at this new one as a completely different character for now
