The thing that sucks is that 8 tails got beaten that easily,(yeah Amaterasu is strong but if it is so strong it should have killed Karin also)
Amaterasu isn't an insta-kill technique.
I personally believe he does have the EMS due to gaining Itachi's eyes and techniques. Also he has six tomoe-esque things in his eyes. I would assume that having Itachi's eyes and the formation of a new MS would mean that he has EMS. Can't be too sure though.
As for what the EMS does, that is why I put it is slightly possible.
Also for the people who don't understand how Amaterasu works think about it as a little fire that rapidly grows bigger and bigger while burning endlessly. It is a technique that gradually does more and more damage, not instantly.(very quickly though) I am assuming that Sasuke teleported Karin away from the burning flames in time. She was knocked unconscious though.
I am an Uchiha fan. There I said it.
Now that Itachi's dead I will never get out of this genjutsu.
Don't stare directly into any of the eyes.
I don't think so i think he jut has the ablity to extinguish it, like Madara did

I am not perfect and I defy you to prove otherwise
Growing Old Gracefully is an Oxymoron ... Mostly Moron !
I coulda swore we had already known that the 8-tails fight was nothing more than a showcase for Sasuke's new MS and to reveal the Jinchuuriki. Although Kishi did sucker me in to believing the 8-tails had a future beyond being sealed so kudos to him.
