I knew Sasuke was gonna survive but he barely had chakra to move his body, no way he had enough chackra to summon Manda and use a genjutsu strong enough to control him AND then go to the "space" summoning creatures are. All this in less than a second... I wouldn't had mind if he summoned Manda before Deidara used his ultimate attack.
Also it seems whoever the guy in the shadows is, is the true "leader" of Akatsuki. My cousin thinks the members are being tricked to obtain the Bijuu and then the real plan will take place.
