The end of the world. It will end on 21.12.2012 and we will finally know what the Mayans meant when they created their calendar and stopped at this great tragedy. They too thought life won't be worth living afterwards xD I mean, why would we need calendars if not to mark the new chapter/episode's release P:
I don't think there will be another series. However, I remember reading about a new Naruto manga. I think that it's called Naruto: The Next Generation.
