I am not looking for a flame war .
Since Orichimaru was revive by Sasuke,Orichimaru have discover a new path to follow anything that Sasuke decide.Orichimaru was concern of Sasuke emotional state during battle against Obito .We already know Orichimaru is a very good researcher and a medical type of ninja,why Orichimaru said that Sasuke will surpass Madara ?I believe Orichiamaru know what Sasuke true potential and his current EMS power capabilities from the time he was Sasuke teacher and the time gather information kabuto dna/chakra.This is why he will not risk himself to Challenge Sasuke at any point even at Orichimaru current Stage(dsm,senju,hand jutsu restore) because Current Sasuke is fighting very well on the battle field and he still holding back his powers at the same time.Orichimaru donot know what Sasuke have hiding ,so it better he follow his order or than to potentially get defeated by totsuka blade again(since he have itachi eyes)
