I don´t think it makes sence to post here ´cause the thread will come again and again, but i am doing it.
I agree with the most people who say that Pain wins. Seriously come on guy´s. The only thing what we saw where the special abilities that pain have, but did we see any of the six paths fire, water etc.?! no we didn´t.
Also Pain usesd most of his chakra for the konaha will die bitches jutsu

... So seriously i don´t think Sasuke will stand any chance against Pain.
PS: Genjutsu? The only thing sasuke did so far with genjutsu is letting believe danzo that one eye on his hand is still open i don´t think that he can do anything with genjutsu against so many pain bodies.
