Orochimaru said something like "I still think Kimimaro's body is the one I wanted more."

People have questioned why his body would be better than Sasuke's. Sasuke has nothing more than a good body for a nin, while Kimi's body is perfect for one. That's not the same as having Sharingan, which we know is "portable" as long as you don't mind killing someone and taking their eyes. We also know that Orochimaru doesn't have qualms w/ either of those. (Eyes just taste better, right?)

Kimi's level two is going to be sick.
