I still don't think they're on that level yet. Have they ever even shown Beerus powering up? This is a dude who destroys planets in his sleep (literally). He erases Gods effortlessly. He also seemed unfazed by Goku's power in the last episode.
Goku and Vegeta have to power up to SSB and they can't stay that way for long. Beerus is always at high power level and we've yet to see him really exert himself.
true, but beerus hasnt been training...so even though we havent seen him use all his power, his highest power hasnt changed...it was 10 when we met him, it's still 10 now....where as goku/vegeta have been training, increasing theirs....which shows in how easy they go, stay longer, and increase their power level while blue now....
and you right, he seemed unfazed last episode, but he was fazed when goku first showed the blue/kiokan (sp) mix....plus, you saw goku wasnt fazed when beerus got serious with him, which tends to get me thinking he got something up his sleeve...
...just saying, i think if they went all out, the level between them and beerus is a lot closer than people might realize....
