In my opinion it won't turn that way...
I think and I'm almost sure that it will end in something like this:
Naruto will fight Sasuke and somehow he will show him that he is wrong and Sasuke will be converted to the good side once again.
And then, Madara that's getting too powerfull will be too much for Naruto to handle so he will need the help of his best friend, Sasuke, and it will end in a Naruto+Sasuke Vs Madara fight.
I have very good reasons to believe it will end this way, one of them is because of Madara's sharingan, that can control Kyubii as we know that he did so in the past, I won't say the other reasons I have to believe it will end like this because I don't want to spoil people that doesnt read the Manga...
