I believe after or during sasuke conversation with the edo kages,Tobirama (knowingedotensi jutsu )will break out of the jutsu and free the others by using a jutsu on Orichimaru to break the control.As a result we will see the most epic battle in history of manga
Hashirama vs Sasuke :
this will show us that sasuke surpass EMS madara if he won compare to madara battle with Hashirama in the pasts
Hiruzen vs Orichimaru:
Both orichimaru and hiruzen know alot of jutsu or have alot of feature in battle.They will battle it out to the end,age will not affect hiruzen because he edo tensi.
Tobirama vs suigetsu (both water type)
Probably suigetsu will learn some water release and also will collect tobirama sword called sword of the thunder gods for his collection in the end\
Remember when someone in edo tensi form ,their weapon is also return to it owner and it original form (before the user die)
Minato vs Jugo
I donot know what similar between there two but both will not have anyone to fight since orichimaru and other will be occupy.Probably Jugo and sasuke will fight Hashirama and minato .Since it is jugo job to look after minato.If minato have the ying half of kurama chakra inside him,this mean he could turn to a tailbeast like the gold and silver brother.Therefore we will see minato in tailbeast mode vs Jugo in tailbeast mode.
