I agree Zetsu uses that cloning tech right up to the chakra, He must have something to do with it
interesting, that would be nice if Tobi had something to fear of Naruto
I just re-read Ch490 pg4. I think Kabuto Edo Tensei'd Tobi's original body, as he totally pooped his cloak when the coffin opened, calling Kabuto a "mad Man" which is rich coming him him and his mooneye plan. and Kab stating "you can't refuse me". I'm thinkin' that Tobi needs his real body back to be able to return to it, after using So6P power to restore life into the dead flesh.
sorry if that last part is thread jack... I'm still makin may way around here and cant' really keep up with all the different threads
