To make this short & brief..
Madara plan to loose the fight with the 1st hokage ( and die while fighting him )
To take the 1st hokages DNA and combined it with his own creating Rinnengan
while Madara was dieing from the battle wounds he told his brother Izuna ( Tobi ) to take his eyes and grow them in a Uzumaki Child ( Nagato ) for only an Uzumaki can learn to control these eyes (Unless you have Senju & Uchiha DNA MIXED ) He than told his brother Izuna ( Tobi ) to have Nagato grow to bring him back to life however things did not go as plan. Orochimaru was also trying to obtain the powers of Ridoku as were the Uchiha Brothers ( Madara & Izuna ) Orochimaru taught all of these things to Kabuto for him to fulfill if orochimaru was some how defeated ( sealed by itachi ) .. However Izuna ( Tobi ) may still not act as he & his brother plan so Kabuto told Madara that he is on his side ( Knowing Madara is the most powerful Shinobi on the battlefield next to his brother Tobi and what Naruto & Sasuke will become )
Prepare for Madara's Edo to end after some revealing information & also prepare for Orochimaru's return after Itachi's battle will Kabuto in which his Sasunoo will be summon and his Totsuka sword will finally be in the hands of Orochimaru who will not longer be sealed.. From there it will lead to an epic ending.
