maybe but there are still to much questions. for example why show sasuke with the mangekyou how his parents and other relatives died? and what does akatsuki have that itachi want? and when the akatsuki is drawn into this you could ask, did the akatsuki kill his family becuase he refused to join? and did he join in order to protect sasuke? maybe itachi made a deal with akatsuki, i will join, but dont hurt my brother or something like that since sasuke was lucky enough to survive the massacre.
