Nahh Oro has no need for an apprentice and he already has Mitsuki. Oro's new CM is probably given to the elite ninja squad that Kawaki and Boruto are a part of.
Ok , I'll give you all rumors I heared about Boruto :
_-_ :I do not believe that Orochimaru really becomes a good kid and don't do bad things ...
_-_ : Orochimaru used Toneri's genes to create Mitsuki (Artificial Otsutsuki ; like how he created Shin): Looking at Mitsuki , resembles me of Toneri ..... (Oro traveled to moon and stealed some of his genes ... WHY ? Because he must be Kaguya(Hamura (Toneri) + Hagoromo(Sarada + Boruto)) to reach his dream )
_-_ : Orochimaru is the villain and he's trying to steal Boruto and Sarada ; he isn't capable of doing this now (Because Naruto and Sasuke would one-shot him) ...
_-_ : Orochimaru strengthens his CM (what we saw on Kawaki's hands , I think was Oro's new CM)
_-_ : Orochimaru wants to take Mitsuki's body (when he is strong enough) and then attacks Boruto and Sarada and steal their body .
_-_ :Boruto understands Oro's plan and saves Mitsuki .
_-_ : Orochimaru sends one of his apprentices (Kawaki) to take Mitsuki back . (because he himself can't fight well ; because his body is at bad condition)
_-_ :Mitsuki hides and Kawaki kills Naruto and most of the people of the leaf and Boruto arrives .
_-_ :Boruto somehow managed to take Oro's new CM and is able to control it .
_-_ :Boruto awakened the Byakugan and got access to Mitsuki's genes ; So he'll awaken Tenseigan .
_-_ :Sarada will awaken rinnegan (getting DNA and Chakra from his father)
_-_ :Sarada will learn Sage Mode . And was learning Sage Mode when Kawaki attacked the village .
_-_ : Orochimaru would become stronger than Kaguya but loses against Team 7 (Mitsuki + Boruto + Sarada)
_-_ :Sarada and Boruto marry and their child : his face would be like Minato , he would be cool like Itachi .... And would be the first one to have Rinnegan + Tenseigan ...
