I like Naruto because he never gives up and he always works hard for what he had.When people treated him like a nobody he did'nt let those people get him down and Naruto proved them wrong by defeating Pain.
The kind of power-ups I'd like to see would be a hybrid version of BM/Sage Mode and some Uzumaki techniques.
I support Naru/Hina 100% because I feel like they were made for each other.
I want him to be Hokage but I also want Naruto to travel the world and spread his message of peace to everyone he meets.
As for him being the next Sage...it is possible since Naruto carries the Sage's dream of peace but think something like that would go to his head.But Naruto IMO is already the next Sage in spirit.
