well i predict tat over the next 3 chapters. there will be talk n fighting amongst madara, tobi v kakashi,guy, naruto, killer bee
but then wen everything falls apart n our heroes are beginning to lose.then boom . outta nowhere sasuke, orochimaru, suigetsu n juugo will appear!!
(this is after all, AFTER they've returned from the "people who know everything")
after this they will assist in fighting for the greater good or bad. your choice aha :D
