The title say it all but you guy have to be humble.Kishi end the obito's flash back early because he donot want the fans to get fed up like itachi explaining izamai to us.I believe sasuke will get all the info about madara before he fight him.Since sasuke maybe dont know who the mask man then we will get an explaination of why obito kill the uchiha clan.Other plot holes will be clarify.
