The cult comedy will return in 2013 on Netflix, but creator Hurwitz confirmed to Vulture that a planned movie spinoff has not yet been "sold".
"The episodes are an outgrowth of the design of what we hope will be the movie," Hurwitz explained. "They precede it. They function as an act one of a movie that we all want to do, but haven't sold yet.
"The episodes take the audience through the experiences of the characters since the family fell apart and how they're brought together to deal with their new problems."
Arrested Development star David Cross recently claimed that the Netflix season had been extended from 10 to 13 episodes, but Hurwitz maintained that the "initial order" is still for just ten instalments,
"Our initial order is for ten, but the beauty of Netflix is that we theoretically have an opportunity to provide more material for them," he explained. "We're definitely shooting some special material just for them."
Arrested Development originally ran for three seasons on Fox between 2003 and 2006, earning six Emmys and a Golden Globe.
