The manga has shown sasuke and orichimaru (finally i should add) and alot of us have been waitin quite eagerly for it. My theory is that whatever orichimaru has to show or whoever they want to meet(although thats very unlikely imo) will not change sasuke. But after that orichimaru will try to kill him. Ofcourse Orichimaru wants revenge. I mean the guy spent his entire life in the attempt to become immortal and found the perfect vessel for himself only to be killed by the vessel. Sure orichimaru knew that sasuke wasnt going to be loyal to him but he must have underestimated him. i think that orichimaru will double cross sasuke and sasuke will kill him once again. then he will head to the battlefield and get rid of Madara. Then naruto will have to get rid of sasuke and when he does that he'll be declared the new sage of six paths!
