No it was not stated as far as I recall, HOWEVER, remember that Madara Had spent years planning for all this stuff. He even prepared a Hashirama clone (presumably for himself), and He was linked to the Mazou (Juubi's inactive body) for decades. My guess is that Madara has the Jinchuuriki part all worked out and ready to go, the only thing he needed was for a Sucker (Obito) to perform Rinne Tensei.
