I'm not entirely sure if Team Asuma is going to be the one to finish of the Akatsuki duo. I mean, honestly, what can one team do against an immortal person? However, if Asuma used the technique that the 3rd used against Orocimaru's arms, I guess it might kill him. Plus, it would make sense with all the foreshadowing of Asuma's death. Might as well be a sacrificial jutsu, compared to just getting owned, eh?
