A thought;..... Minato fought the fake Madara when Naruto was born. If the fake wouldn't have left Minato would have killed him. PERIOD. There is no need for debate. He had his timing down and if he didn't have to 1) Fight the nine-tails, 2) protect his wife, 3) keep his son away from a madman, 4) protect the village, 5-00) then he would have killed Tobi, who everyone is saying is so powerful.
Let's line them up strongest to weakest:
Harishima > Madara
Minato > Itachi
tobirama > Sasuke or Madara's brother
and we haven't mentioned Naruto yet!
The Uchiha's have these fancy eye powers now, so what. The people they are fighting are too fast to be affected or caught up in it. Naruto will not be caught up in any genjutsu because the nine-tails will counter it.
Come on now, Kishi keeps giving the Uchiha's more and more power to measure up to the Senju's by lineage, not by manufacturing stolen power from the Senju. They have to feed off each other's eyes just to compete at the highest level. They are invincible against everyone else, but don't go up against a Senju, they will get their asses handed to them.
