I'm actually pretty surprised that Kishi decided to take this route. It's a little degrading for Itachi's character to have to explain himself to Sasuke after everything he did. And its a little degrading to Sasuke's character to have him chase after Itachi and say, "Hey, wait up brother!". I just think it makes for a long winded convo (as we saw it begin today) and little after-effect.
I think it would have been far more interesting if Sasuke simply found out later that Itachi had been edo'd, and never actually see him. Anyway, this chapter is a 3/5 for me, hopefully next chapter we see something new in the 5 kages battle and hopefully Sasuke and Itachi will go different ways, or Sasuke will team up with him.
