If you count the number of light in the map at the end chapter, there are only 34 of them.
As you know Kabuto's edo tensei army consist of 38 shinobis.
Sai's brother and Sasori already released. Who is the rest two who still roam free ? Is it possible if two of them Madara and Muu ? Or is there any other else?
this is a good thread compere to the others
You can see theyr all leaving
+rep for noticing
If Madara vanished too it would be stupid.. but believe me Kishi can do it to pleased all of Itachi's fanboys including himself xd
good theory, but I dont think that will happen, some of the edo's are disintegrating when Itachi released it
