Yeah at this point they've pretty much confirmed these two can destroy the universe and that the true power behind SSJG is that it just keeps getting stronger. It's less a static multiplier like x50, x2, x4 but like a formula. E</=B*X where the E is enemy, the B is the base power level for Goku, and the X is whatever is needed to make B equal or better than E.
Also I really don't think arguments against the universe getting destroyed apply any more. Old Kai flatly believed both him and Kibito Kai were about to die and they technically exist outside of the universe. All of this from residual energy from Goku and Beerus, not even the main amount of strength.
So yeah pretty strong. I mean the episode was a lot of screaming and fisting but there was a bit of traditional combat near the end. I've long accepted that I'll just simply find the manga more entertaining because the speed but I can deal with the anime being ridiculous like this.
Also does anyone feel like Toriyama saw the Death Battle and got pissed that Goku lost?
