i dunno... sasuke getting Rinnegan seems a little farfetched to me. I think maybe Madara needs rinnegan in order to control the beasts, u no, with the war and all, Madara said he would use the beasts to defeat the villages.
Predictions:
1. Naruto wakes up and has talk with Kakashi and Sakura
2. Madara begins transplant with itachi's eyes and disappears to get Rinnegan
3. We see short speeches from Kabuto and/or Kisame about their plans
I think in the future, Kisame is going to get 8 tails and then try to kill Raikage/do some damage to mist village
I dunno what Kabuto is doing...he doesn't really have grudges against anyone except Akatsuki/Naruto... so this is my prediction. He will join Akatsuki and plan to kill Naruto to ruin Madara's plans, but Madara will find out and send Sasuke to kill Kabuto instead. I think this would be a cool fight and storyline so I really hope something like that would happen.
