That translation is incorrect. Madara actually says; "Not even a Bijuu has this type of power."
And yeah, I don't think Madara will dissipate like the other Edo Tensei zombies are about to because for one it didn't show him as the others started to glow, but the second Tsuchikage states that his consciousness returns, so my theory is, in this split second that Madara has his consciousness, he'll perform a jutsu to ressurect himself fully. And Itachi walking towards Sasuke, I don't think he's going to go transfer more power to him, just poke him on the forehead and say good bye
