According to a guy on the Eric Andre subreddit, he saw Eric at a show and Eric said on stage that season five is coming.
Just started watching this show last week and I'm disappointed I sat on this for so long. I knew Eric Andre was insane but this absurdity is right up my alley. Finished season 2 the other day.
I'm not really sure what the goal is exactly with the show but I think it's definitely top tier of television surrealism and satire.
