Thanks to IGN we now know the title for the opening episode of Book 4 Balance, "After All These Years". It also more or less confirms that this Friday's premiere will be just K401.

Here is the clip http://www.ign.com/videos/2014/09/29/the-legend-of-korra-book-four-opening-sequence-three-years-later Some very interesting stuff going on in this clip which IGN mention is the opening scene of the episode. Immediately it makes me wonder where the other clip with Korra leaving set 3 years before this takes place. We get to see the Earth Prince, named Wu, Gommu returns, plus some better looks at some of the older designs for the characters we already know. Thoughts?
