They will disappear. Leaving no traces and maybe be forgotten. Until Dragon Ball GT... err... Naruto 3rd, when their couple of kids will show up to terrorize Konohagakure.
My prediction that I find reasonable:
I wonder what Kabuto will do to dont look the way it looks now ._.
well dont u think that it will be weird that a White Snake-skinned man with a snake coming out of his belly take care of little orphans? ._.
That form is his sage transformation, he looks normal when not using senjutsu.
He stills look white snake-skinned without sage form isnt it?
No. Recall back when Orochimaru sucked out senjutsu chakra outta Izanami-trapped Kabuto and the latter turned normal. Kabuto looks like a snake only when using senjutsu.
