Well I just don't see Kakashi dying anytime soon...there just seems to be too many holes in his story to die just yet. While Jiraiya may have died figthing Pein, there was never really anything about him that needed to be cleared up. The only thing that needed to be explained was exactly how he knew Pein and how he became the toad sage in the first place...which was still explained before he died even if only right beforehand. Now if in the next few chapters Kishi goes back to Kakashi's past and explains what happened to Rin, how he got MS, etc then he most likely will die very soon. Just my input on the subject
