What will Naruto do without Sasuke?

[Tennis Robot]

I think you mean "concerned" instead of "concerted". Also I'm sure Naruto will reunite with Sasuke or figure something out to contend with Kaguya

 

[Xāvî1]

Naruto is strong so don't fret about it man!

 

[Maly]

He will finally grow up and stop running after Sasuke?!

 

[NukaCola]

He will remplace him for Obito.

He will finally grow up and stop running after Sasuke?!

Highly unlikely. The first thing he'll do is try to find sasuke asap

 

[Sage konohamaru]

No more fodder distracting naruto
