I agree it cant happen. Sasuke had more or less understood everything Itachi did was for his little brother (Sasuke) own good, for one day, Itachi hoped Sasuke can bring glory back to the Uchiha clan.
Obviously Sasuke is doing it the wrong way, or he could be just pretending to be a bad guy. He might have to act a villian becos he knew the multiple Zetsu could be anywhere spying on him. (We since learned Zetsu have the ability to mimic any chakra and thus detecting/exposing them would be nearly impossible.)
The last page of the lastest manga suggest Sasuke and Itachi will meet again, why not? They are brothers aft all... After learning the truth, Sasuke should have already forgiven Itachi. If anything, Sasuke will be mad at Kabuto for controlling his dear older brother in such a way. Sasuke will get pissed off with Katuto and probably fight him.
In order for Naruto VS Sasuke to happen, Madara, Kabuto and Tobi needs to be gone... but how, we wont know... i cant wait!
