Orochimaru the last villain?

[Sarutobi Sensei]

I WANT THIS. Before either Naruto and Sasuke faces Orochimaru, I'm actually hoping for a Prime Kakashi vs. Healthy Orochimaru.. both of them at their 100%, battling it out with Oro killing Kakashi in the end. That would make a good plot for Naruto and Sasuke(?) to avenge their sensei. I could keep on dreaming.
