I was just re-reading the chapter and I noticed a few things. First of all, this time I actually saw the third clone behind Kakashi. Also, on that panel, the Naruto on the right still has his hands in a hand sign. This suggests that the Naruto on the right is the real Naruto. Later on, when Naruto runs out from behind Kakashi after one of the clones grabs onto him, it looks to me like the Naruto that runs out is the one from the middle, not the one on the end. Thus, I think it may have been a clone that ran out against Sasuke and not the real Naruto.
Also, the fact that Naruto makes two clones and not only one suggests he may actually be using Fuuton Rasengan, since he would only need one clone to make rasengan, and the third Naruto is kind of extraneous otherwise. The small size and swirling in the air around the rasengan in this chapter also suggest to me that it was a actually a fuuton rasengan. This is critical I think, because fuuton jutsu are strong against lightning...
Both these things suggest, to me, that Naruto has a plan and is not just acting on whims and feelings. He is thinking clearly, and has clearly made his decision. Exactly what it is, we will have to wait and see.
I also think Kakashi was a little wishwashy over whether to tell Naruto to leave or not...He was adamant about Sakura leaving, but sometimes told only Sakura to go, and other times both of them...kinda funny.
P.S. Did anyone else feel like Naruto was going to grab Sasuke's hand in that panel with just their hands?
