Funimation stunned a packed audience at Anime Expo 2017 this weekend when they announced that Attack on Titan's Season 3 would premiere in Spring 2018 rather than later in 2018. Rumors were circulating that Wit Studio would be releasing the season sometime next year, but no one was expecting the turnaround time between the second and third seasons to be so brief.
While there's been no formal confirmation from Wit Studio regarding the time frame for the show's return, but it was no surprised that fans were both surprised and skeptical of the Attack on Titan announcement. Though the series originally made its debut in 2013, fans would have to wait until 2017 for the show's second season due to continued delays as Wit Studio. With the growing success of Attack on Titan, Wit Studio has doubled-down on prioritizing the anime — particularly important when you consider that Season 3 is expected to have a 25-episode order.
For those new to the series, here's a brief rundown from the Attack on Titan Wiki:
"Attack on Titan is set in a world where humanity lives inside cities surrounded by enormous Walls that protect them from Titans, gigantic humanoid creatures who devour humans seemingly without reason. The story centers around Eren Jaeger, his adoptive sister Mikasa Ackermann, and their childhood friend Armin Arlelt, whose lives are changed forever after the appearance of a Colossal Titan which brings about the destruction of their home town and the death of their mother. Vowing revenge and to reclaim the world from the Titans, Eren, Mikasa, and Armin join the Scout Regiment, an elite group of soldiers who fight Titans outside the Walls."
Attack on Titan is produced by Wit Studio and Production I.G., with the first season having aired in Japan on April 7th, 2013 on Mainichi Broadcasting System. FUNimation Entertainment licensed the series for English distribution and streams the series on its own website as well as with Crunchyroll. The second season debuted in April 2017, with a third season announced for 2018 at the end of the second season's last episode.
