Definitely (unless he wants to keep his arm off for some reason). There are too many ways for them to get their arms back.
Juugo can give them parts of himself.
Steal arms from Zetsu.
Naruto might be able to heal it back like he did with kakashi's eye.
Biting karin will probably heal it back as well.
Wouldn't be surprised if Kabuto could replace Sasuke's arm too.
Sakura or Tsunade could probably take any arm from some dead person and give it to Sasuke.
