Naruto shipuudden last episode?

is "episode 218 - nations on the move" (said to air june 30) the last naruto episode that is going to be released ever? i was on wikepiedia and i had a list of all the episodes "supposedly" it ended with episode 218. i just finished watching episode 216 and i just don't think masashi could seriously cram sasuke launching a full out attack on the leaf plus his epic final battle with naruto it just doesn't seem possible. unless each episode is 30 hours long lol
