The newest Super Saiyan form in Dragon Super was Super Saiyan God Super Saiyan, which sounds too long and silly. That's why it was renamed in the manga back in October. Now, the latest episode of the anime is following suit.
The form revealed at the feature length film Dragon Ball: Resurrection of 'F', is when a Saiyan acquires the power of a Super Saiyan God and then becomes a Super Saiyan, and it's called Super Saiyan God Super Saiyan (???? ???? ??? ???? ????) or SSGSS.
In the latest episode, Vegeta fights Cabba and then transforms.
After Cabba says, "Blue...", Vegeta tells him, "This is the latest [form] Super Saiyan Blue." He didn't explain further as if SSGSS never existed. After that, Cabba says, "Super Saiyan Blue?"
Then Vegeta tells Cabba that if he trains hard enough, he can reach his full potential and transform into Super Saiyan Blue. Vegeta then beats him up.
