Freaking awsome!!!

This chapter raises a lot of questions.
I wonder how strong those summonings will be and how long they will last? Oro's summoning of the 1st and 2nd Hokage was not as good as the real ones(based on what they could do and their might. 1st defeating Madara for instance) and they only lasted one battle(even though Sarutobi sealed them).
Doesn't Kabuto need several bodies to make those summonings? Why did he leave those waterfall ninjas behind then? Maybe he just need stock up on their life energy or something to do it.
The only one missing was Hidan. Does that mean that Kabuto only can summon peoples whose dead?, meaning that Hidan is alive and that they will retrive him later on? And if so, then that confirms Itachi being 100% dead
Will Akatsuki become as strong as before(omg! don't say that?! Pain invation all over again only with more Akatsuki members!

) and will they really be alive again or just limited to follow the summoners will?
And can Kabuto go on terms with Sasuke or does he have a secret plan?
Still no sign of Jugo, Suigetsu, and Yamato:-/xd
Can't wait untill next time!
