Good old kishi most have absolutely no idea what he's going to do with the big conflict between naruto and sasuke simply because these past few chapters make it seem like he's stalling for time. I can just see poor little kishimoto is over there in japan thinking to himself.

"Crap, I've written myself into a corner. What should I do now? Maybe I should have a really really big rasengan."

Probably in the next two to three weeks Kishimoto will get around to doing a full body reveal of Sasuke. That's the best we can hope for.
