Remember Itachi's remarks about not trying to do everything yourself no matter how powerful you get, and then the Sage spoke about how dangerous it is to give one person too much power because it leads to arrogance.
Sasuke is showing all the signs of the arrogance that both of them spoke of, Madara also recognized Hashriama but he still became corrupted by power.
And in a Shounen manga, that just screams that this won't go well for Sasuke, one thing that happens a great deal is that when a character acts like this in a manga about the power of friendship, its inevitable that he will be fed humble pie.
