I liked this chapter, Kurama taking over Naruto in the switch-a-roo was kinda cool, and Naruto talking to Tobi/Kurama about the ten tails is heaps better than listening to Sasuke and Itachi going on, and on, and on....
I thought Tobi might need Sasukes eyes to perform the Infinte T - Being his eyes (itachi's) have been the only ones shown to have been able to use the Technique. But it does not seem to be this way. If he can activate the technique then should not Naruto and Bee be able to get out of it using the Bijuu, perhaps Madara and Sasuke aswell? Sasuke has shown he can break it, so why not then? That could set up an epic fight, with everyone else in the Ninja world in a Genjutsu. We could have Sasuke, Naruto, Bee, Madara and Tobi all free to duke it out without any outside interfearance. Tobi could get all cocky and start showing everyone in the Genjustu the fight, only to lose to a Sasuke/ Naruto combo - redeeming Sasuke, and ensuring every single Human on the planet would see Naruto save the day. That would make a nice ending IMO.
Its just about confirmed now that we will see behind the mask in chp 600.
As someone said earlier, why does not Bee just fire off a Bijuu bomb into the Mazou while it is having its little mental breakdown? That would solve a few things - at least check the durability of the Statue.
