awesome chapter 5/5.
1. now we know that sasuke won't awaken the rinnegan, and since kishi always makes naruto and sasuke equal, as it stands now naruto would win in a fight against sasuke meaning naruto's power will be reduced meaning he will probably loose the kyuubi.
2. out of all the theories no one could mention tsukyomi as the reason obito got so strong.
3. so nagato's eyes were really madara's and the reason for that was because he was the only one apart from madara able to summon gedou mazou.
4. black zetsu is finally explained.
4. naruto is going to loose to madara and kakashi is going to die.
