I'll be waiting, be sure.
Maybe, if you pay attention to some madara's pics it shows only his right eye while tobi(who i think is madara's bro) has the left one shown(madara might have taken only one eye). Mad's brother might have took posses of Obito's crushed body and repaired it with Zetsu's help, then after years infiltrated akatsuki as Tobi and seeks revenge by taking Sasuke's eyes(that are said to be more powerful than Itachi's) and beating Madara.
Itachi is Madara's favourite.
Sasuke is Mad's brother's favourite.
