I have a feeling naruto and minato will have a fight
Aye.. I got the same feeling..
A fight where Minato still got his mind intact, but not his control over his body.
So that he can guide Naruto, and tell him how proud he is, and perhaps teach him an Uzumaki sealing technique to seal him (Would give a good oportunity for Naruto to learn something from his old man

)
And it would show that Naruto have indeed surpassed him - although the fanboys (myself included hehe) will state that Minato wasn't at full power due to him being controlled
