While browing Reddit today, I came across a rather interesting entry that basically showed a tweet from April Stewart, a voice actress from The Legend of Korra, that said that we fans would have to wait until April to hear more from her about the show.
Speculations have said that, as a result, April 2013 could be the release date for Book 2 of The Legend of Korra. Some are skeptical because they believe that April 2013 will instead be some sort of Book 2 reveal.
Either way, it looks like this April will be a month of high anticipation.
