No more real fighting between countries and Naruto is the hero of the war, you can expect some serious growth after that.

This could be just another cool thing they added like the one piece skull on Naruto Hokage face.

well without constant strife and hate between the villages ideas and new innovation can spread quickly and develop just as fast so this must development in 10 years is believable also i assume that ninjas now are the army/police for the city and or body guards for royalty and diplomats.
