No "a bit early" about it. Kabuto fucking stated "Those whose souls are not in the pure world, those whose souls are sealed somewhere else, cannot be revived"
. The fact that Kabuto has Madara as an Edo means that his soul was in the Pure world, not this world. Tobi is not some fragment of Madara's soul bound to a new body. That idea was eliminated the second the real Madara was shown to have been in the coffin. Further debunking the "split soul" idea is when Gaara points out that Madara was brought back by Edo Tensei, which meant that he was dead before
