( I don't know about your future scenes but I keep envisioning a final battle when naruto, who has established his title, and his loyal anbu hunt down sakura for a final confession of her sins only to encounter that Itachi has also caught up to her as well...pretty weird huh?)
Sakura confessing her sins? Well - I would say we haven't heard the final story about what she has been doing in the Rock yet. Naruto doesn't now - and he doesn't know that he almost killed Sakura when going Kyuubi.
Yes, defiantly too many loose ends.......but I am glad that someone will follow it to the end! makes me happy!
