So, How do you think Itachi knew that sasuke was going to go after kohona?
I think it's because he'd been watching Sasuke since he was young, so he pretty much knew how Sasuke's mind worked by then (i.e. easily influenced by his emotions). Also, Itachi has been around Madara for several years, so he also knows how Madara operates, and that Madara would do his best to influence an impressionable, confused Sasuke to play into his hands.
On a side note, I thought this chapter helped to answer a lot of questions (e.g. What did Itachi say to Naruto? Does Sasuke have EMS? How is Naruto powerful enough to beat Sasuke, now that Sasuke's uber-strong?...), so I'm adequately appeased... at least until next week.
