Orochimaru will have his time to shine as a villain before he gets TnJ'd by Sasuke or gets killed for the last time.
But I can see what his pawns will have.
can you see the picture of his experiments?
One eyed Zombies with Sharingan enhanced by Senju and uzumaki DNA. He gets all the ingredients from...
1) The ruins of Tobi's hideout.
2) The flower seat of Gedo Mazo.
3) Karin ( he saw Karin's development when she went ape mode against mini-shinsusenjuu and I believe she'll play a huge role from getting killed by Sasuke during Sasuke vs Danzo till dying for Sasuke by orochimaru's hands )
