Here's what I think is going to happen to Sasuke. Sasuke is going to get strong, very strong. You could see that Kabuto was worried in that last chapter. I think that he's going to get nearly as strong as his brother. But I do think that he's going to rely on the curse seal to much and not be able to kill Orochimaru. Eventually Sasuke and Itachi will fight once more. It will be a battle but in the end Itachi won't kill Sasuke. I think that Itachi will only be there to teach Sasuke a lesson. He will force Sasuke into not using the curse seal. Because I think that it will only end up holding him back in the end. He will finally manage to supass his brother and hopefully return to Kohona. And in my perfect world him and Sakura would finnaly get together.
