When does The Ricky Gervais Show return?

The Ricky Gervais Show is an animated version of the popular audio podcasts and audiobooks of the same name. The TV series consists of past audio recordings of these unscripted "pointless conversations," with animation drawn in a style similar to classic era Hanna-Barbera cartoons, presenting jokes and situations in a literal context. There were plans for a possible fourth series which would have used newly recorded audio, but this was shelved in June 2012.
