There is no word yet on whether creators Mike and Bryan will be making an appearance (or other voice actors, for that matter), but we can confirm that Janet Varney will in fact be present.
Conventions like these are generally highly anticipated because they are almost always a source of news and information for whatever product promoted. At the San Diego Comic Con, we receive tons of news for movies, television shows and games. In fact, Comic Con 2012 was the last time we received official Legend of Korra information.
I think we should be expecting the same thing from the Anime Matsuri Con.
The Anime Matsuri Con could be huge for Legend of Korra fans because it will likely reveal any last Book 2 information that hasn’t been release already. That means if we haven’t received a Book 2 release date or trailer by March 29th, expect the Anime Matsuri Con to be responsible for releasing that information to us.
But we’ve been disappointed in the past, so I think it’s important for all of us to keep our expectations low. Despite the fact that I expect to see some sort of imagery of Book 2, it is still possible that Janet Varney will simply talk about Book 2 rather than show us Book 2.
Is it likely? No. Is it possible? Yes.
But the one thing I know we’ll be receiving from this Convention is Book 2 information. No matter how Janet Varney goes about conveying Book 2, we will still get news. And not just any news, OFFICIAL news.
