Yes that is correct, it looks like the fillers finally have an end date! The magic date is July 18th with episode 321 "Reinforcements Arrive" Finally finally finally this crap is over and the real story continues. And IF and I mean a big if 321 doesn't end the fillers (I believe it will be the episode where Naruto finally enters all the battle fields) 322 is definitely the end because it is named "Uchiha Madara"

All I can say is finally finally finally it is over!

Sorry for the long load times
