So there was a trailer released after this week's Dragon Ball Super for the upcoming Universe Survival Arc and there is a short transformation of what appears to be a female Saiyan transforming into a Super Saiyan that looks like Broly.
Link to the video (Go to 0:18) for it-

It's not in a good quality, so it could be different version of Broly that isn't female but once we get more into the arc and see if it is the first female Super Saiyan.
If it is, Hooray
If not, then I'll either ask for this thread to be moved or deleted
