With uchiha shisui's eye tech extinguished there is no way for sasuke to get hit with the genjutsu from shisui's eye. Unless they use some way to say naruto can use the 1st's cells/blood etcto revive the technique. It is for the better if the tech stays done for now anyways. Now sasuke can show up se his brother stay unswayed from the speech then have naruto fight him and give him the ultimate shonen speech then Madara takes a cheap shot at weakend naruto.....he goes to finish him and complete his plan when....REDEMPTION! Sasuke is good again! Good ol friendship speeches and bonds that can never be severed. Ninjas arent tools speech, final rasengan/chidori tech, and roll them credits as the 4th ninja war comes to a close. Where ever they end that battle will be the historical landmark of their time like the valley of the end.
