Okay guys yesterday I watched this YouTube channel called foxen anime and it was a video about season 3. So it tells how he was at an anime expo in California I think it was CUS I saw it on the maps of events on Snapchat. Anyways he went too the aot area and asked the producers about season 3. They said it was coming spring 2018 and then he asked how many episodes it will have. The guys just said they'll be working really hard.

Here's the video if you wanna watch it
He explains it better than I do
