Itachi's Purpose will be Short-Lived
Hmm, in terms of ocular jutsu, as we are moving up the realms in the the EMS and Rinnegan stage, considering Itachi has a regular MS, I don't think Itachi will serve to much purpose against Kabutomaru.
Although I want him to, I don't think he will because he's already dead in a way and this his Mangekyou is being showered down at the moment.
However, he is the fan's favourite, it's possible that Kishi may make him do something epic though.
Although, I really don't think he'll meet Sasuke, maybe for like a split second and then he crumbles away.
What do you think?
