Well, they showed Chiyo as well, and she looks like the exact same old woman she did when she died.
Well, Kabuto has had these bodies for awhile, and he seems to be able to reanimate them and deanimate them at will. So presumably, he could bring them back, allow them to gear up, then put them back to sleep.
So I would presume he would have obtained SOME equipment for Sasori at least. Doesn't do a lot of good to bring back a puppet master then not give him any puppets.
