On the real... Kakashi is the shit and I don't think he's gonna go out like that. But I bet this battle will be the loss of his Sharingan. I'm guessing something will interrupt Pein from finishing him off (like finding out Naruto ain't in the village...).
Kakashi gave Pein and run for his money, though. Jaraiya would be proud...
EDIT: Whoa whoa ZenkiKid... what is this bull**** you are printing? The great majority of your comments are completely false...
