While Sasuke and Naruto are going to surpass Madara and the 1st Hokage, I doubt even they will make Madara look like a "joke". Madara is far to broken to ever look like a joke unless the person has God like powers and can just kill by just thinking it. That's about the only way I could see Madara being made a joke. But yeah, Naruto and Sasuke are set up to being the most powerful ninjas of their generation, past and present.
Parena or Serecham both equal Serena+Pancham! Sereevee or Serevee equals Serena+Eevee!
