The manga is currently on chapter 396, the anime storyline is currently in chapter 312.
This means they're 84 chapters ahead, which means at a rate of 2 chapters per episode they would need 42 weeks of naruto to catch up to where they are, at which time (unless I've done it wrong) there should be 35 new episodes (based on 2 chapters each) up until they catch up which means 77 weeks of naruto....
Whiiiich equal 539 days without break before it catches up to the manga...
Or something like that in case anyone was wondering. =P
