my beliefs are simple:
1: the meeting, everything will go somewhat normal with danzou being a doosh, untill sasuke shows at which point naruto deals with him.
2: as for naruto's next teacher, it will be either the eight tails or his mother, his mother for water or the eight tails for better beast control
3: dealings with the eight tails, he will probably show at konoha trying to search for his brother(kage) and team or he has hidden his chakra and has been tailing sasuke until he had a chance for a proper attack, this could quite possibly have something to do with sasukes meeting interuption
4: tobi is not madara he is somehow a part of madara, this will be reveiled in some form of dark secret converation that sasuke could possibly overhear turning him against akutsuki or by descovering another uchiha he wants to fight with madara
5: anko becomes a major roll, she was one of orochimarus experiments and of course has ties to kabuto, she will either die in a dramatic way or become some form of hero, another possibility is that she takes on a more evil rol as kabuto releases some form of seal within her to make her into a beast or to bring back her loyalty to orochi, making her a major 3rd party baddie as protector of kabuto
6: naruto, his main focus right now is obviousley relationships he will need to deal with hinata, also sakura could become interested in naruto (recently she has looked at how hes changed and thought about the devotion he has given to his promise, this mainly depends on sasukes actions during/after showing up) another major relationship is his mother and also some form of revelation about his father more than likely through kakashi.
7: sai will play a major role in the downfall of danzou, this will probably take place if/when sasuke is captured and danzou makes some ort of decision about him that angers naruto and through naruto sai, the revelation will probably come in the form of information about itachis true intentions: puting an end to madara's influence on konoha
thats about all i can think of i probably should have put in more detail but each scenario seems to fit the given characters this was mainly just to stir up some thought so... goodnight
