Change. Is it really a good thing? People change, things change and as time goes by we can hardly recognise ourselves. Team 7 changed. At first they were excitable and temperate, Sasuke the cool one, Naruto the fool and Sakura the fangirl.
They matured, each going their own way. There were many possibilities that they could've taken. Many roads they could've walked many doors that they could've opened. They each chose their own way and they walked it.
Sasuke's future was decided the minute he nearly killed Naruto but didn't and walked away. Naruto's future was decided when he accepted Jiraiya's offer to a three year training. Sakura's future was decided when she stepped into the Hokage's office and announced that she wanted to be stronger. They were all stronger now.
Their roads, no matter how far apart they were, had crossed once again. But it was already decided, Sasuke was the traitor, Naruto the Jinchuuriki and Sakura the Hokage's apprentice. They had changed.
They still weren't sure if it was a good thing.
