Now all these questions on the powers Itachi gave to Naruto has been answered... I believe Naruto after Itachi's fight will now face sasuke squarely. I also believe Itachi originally gave the crow to naruto for something we don't know. I think it's an activated version of his powers to protect naruto, since he loved the village just as he Itachi did. I don't think he gave his powers to naruto for this reason, it's just a coincidence that it happened this way. Now with these two who do not know any sealing Jutsu, how are they going to defeat them. If Naruto and Bee are not careful they will run out of chakra and that is going to be a real problem. And to those who are still babbering about Naruto not being able to handle the kyuubi's chakra for so long, here is the trick: he(Naruto) already left a clone when he summoned Gamakiri to gather nature energy for which he sends to the original, similar to Pain's method of controlling his six paths.
So please stop ruminating over the fact that he can't be in the RS mode for so long....I will say Naruto has outsmart all those saying that.
