Oh ya forgot to mention that I felt that the whole pregnancy issue, that while foreshadowed, still made me feel a little disappointed. It's great that Tsunade's fears were unfounded and that she was simply reverting to the age where she felt she was at her prime, and while having an eternity with Naruto is fantastic, preventing the ones who wish to have children even if they had to watch them age was quite saddening. Then again, it's possible for Naruto and Kyuubi to change that 'clause' later and allow Naruto's harem their eternal youth while having the capability of child-birth.
