But don't forget that Sasuke no longer has his cursed seal, which he has relied on in his attack on Orochimaru, his battle with Deidara, and when he went to recruit Juugo. Also, Sasuke has repeatedly shown his reliance on his Curse Seal whenever he runs low on chakra due to him using big jutsu after big jutsu, in particular his chidori related ones. It wouldn't be completely out of the question to see Sasuke actually weaker than he was before, new sharingan or not.
I forgot about that...
True he relied on that seal quite a bit. It will be interesting to see how he fights now. That being said, I think he's still going to be stronger. He might have lost the cursed seal but he gained a new sharingan as well as some of Itachi's jutsu (possibly).
I am still wondering though, if Amaterasu wasn't just a one shot thing that Itachi put in Sasukes eyes to ward off Madara. I mean if it wasn't a one shot deal why didn't Amaterasu keep on firing at Madara after it didn't work the first time? Also wtf is even up with this deal... how can Itachi just give jutsu around. I though shinobi had to learn and practice their skills... poor Lee's hard work just keeps getting more and more pointless... (he always seems to lose his fights).
Kekkai genkai may be different. And maybe Itachi used a jutsu to transfer knowledge of the sharigan jutsu? I do feel sorry for Rock Lee, though. Sasuke will have to learn to fight differently without using the cursed seal for sure. No, he no longer has it. One of Itachi's objectives was to kill the Orochimaru that was inside Sasuke.
What if "the real one" = Pain? Possibly Jiraiya was fighting a lot of copies of Pain. I think that he's realized who Pain is, and it's got something to do with the three kids that he trained long ago, otherwise, why show them? And he also realized that he didn't fight the real Pain.
