UPDATE/ TheFutonCritic has the episode titles for K308 "The Terror Within" and K309 "The Stakeout" which will air July 25th. As we found out yesterday we will be getting 2 new episodes of Book 3 each Friday from July 11th.

Now thanks to ToonZone we have a new episode title as well as descriptions for the next 4 episodes.
K304 In Harms Way - July 11th "After discovering that the Earth Queen is forcing all the Airbenders in Ba Sing Se to join her army, Korra makes a plan to bust them out." K305 The Metal Clan - July 11th "Korra's quest leads her and her friends to the metal city of Zaofu." K306 Old Wounds - July 18th "Beifong is forced to face her past." K307 Original Airbenders - July 18th "Tenzin tries to train the new members of the Air Nation while dealing with Bumi's bad attitude."
Anyone who has seen the mexican leaks will know all about episode 4, 5 and 6, but these descriptions and titles may be new to some. The real news here is that we have the title and description for episode 7. After looking for airbenders it looks like this will be the episode we get them trained, it should be fun to see more airbending training. Thoughts?
