I think that in the end naruto and sasuke will start fighting. but then they will face the ultimate threat. (tobi,madara,kabuto,juubi or something new it doesn't matter)
they will stop fighting and face the threat together and win at the cost of their own lives
then both will be adressed as heroes (and perhaps they will be given new titles)
their statues will be made just like the one with hashirama and madara
but this time not in the stance for battle but in the stance of brotherhood or something like that
about the time
probably the first arc after the 4th war
