Obito implies that even while sick and dying Itachi could have killed Sasuke if he wanted to, he also says that if not for Itachi not knowing his secret(kamui's workings), Itachi would have killed Obito too. Kisame also admits Itachi is stronger than he is. So with no plot protection and taking away feelings and emotions for each other Itachi will kill Sasuke, then move onto help Kisame kill Naruto and with Itachi and Kisame working together they will succeed.
