Ya Itachi planned everything, even his death. So Sasuke could get his revenge for the clan, but he also did it to prevent Sasuke to meet Midara(Tobi). i was serpized when i read that in the manga.
Yeah but all his efforts were in vain. Madara still got to him. But there is hope since Sasuke did say and I quote "we are using the Akatsuki." And we haven't seen him after that and the whole pein and Nagato arch in the manga.
