Ooooooh yes, please, lets start arguing about Itachi!! It's never been done before, and I'm sure everybody must have something smart and logical to say about him!!

The next two or three chapters will deal with Konoha accepting the fact that Sasuke pulled an Anakin and joined the dark side. Given how Naruto was basically the only one that ended with no holes all over his body (fine, so Shikamaru's fine too), maybe he'll be hated again by the village... which reminds me that some people used to say something like "Kishimoto needs to find a new reason for the townpeople to hate Naruto, the Kyubi thing is getting old.", so there's your new reason.

After that, it'll move on to something else - either another training arc or an Akatsuki arc.
If its a purely-training arc, with no other goals, it should be kinda short, but it'll surely be mixed with something else. Regarding Akatsuki, I have the feeling that we'll finally meet some new members and one of them at least will be all like "Hah, I'm stronger than Itachi!!"
NOTICE: I'm not saying he'll be stronger. He could be bluffing, or whatever. But that could happen.

Truthfully, I'd like to see a little bit more of Tsunade. We have seen nothing of her now that she's a Hokage... she just got the job and three days later Naruto and the others go off and we have nothing but forest-fights for an entire year.
