Suigetsu and Juugo are still looming around the area as well as kiba and akamaru. I wouldn't be suprised if any of them saved him. I would prefer naruto to save him from this impending doom but its too early for another sasuke naruto reunion. Plus theres no way we will ever see sasuke look beat down and tattered in front of naruto. I assume well see a team hebi regrouping to save theri fallen leader or some help from konoha. I strongly doubt tobi will help. If he cared about sasuke he wouldn't have set up deidara's land mines. Tobi is interes ting but you guys want too much from him at this point. Just let him be an unknown akatsuki for now.
