I have a feeling this is only the start. For he now has Itachi's eyes and his "Vision". With Itachi's vision, Sasuke will soon be returned to the person who he was before before and I predict just before Tobi is about to take down Naruto, Sasuke and Itachi come up with double Susanoos and smack Tobi down. This is just my idea, also. I know it's off topic. But do you think Sasuke's Susanoo has the sword and sheild Itachi's had? I would make sense seeing as Susanoo's kinda merg when you get the EMS as they look like two stuck into one. But then again, Itachi's Sunsanoo still has the weapons.
