Yea, I'd expect obito to land the final blow similar to Darth Vader.Depends on how great this fight is. I wanna see another Susano'o battle and some more op shit. Then Obito could kill him like Darth vader and the sith, but I doubt kishi kills him.
Obito and Orochimaru are up there for sure. Lol2 out of 10. But that's saying a lot coming from me-obito is one of the biggest trolls in the series.(if not the biggest...)
