Sasuke at a young age was able to suppress the kyuubi chakra with a regular 3-tomoe sharingan and the kyuubi even complimented his eye powers by comparing them to madaras, I think that foreshadows that sasuke will one day surpass madara. But i could be wrong...
And no im not a sasuke fanboy, i believe you assume that because of my username but no i am not one of them.
