Creator Mitch Hurwitz confirmed in late 2011 that the show will return with a series of new television episodes and a feature film in order to wrap up the Bluth family saga.
Howard revealed that the series and movie have yet to receive a start date, but insisted that the ambitious project will begin in the near future.
"There's not a specific start date, but Mitch Hurwitz is definitely working to quickly get it all under way," Howard told Collider.
"I don't want to burden him with any release dates, but I know he's well under way and it's something he's been thinking about a lot, over the previous year."
He added: "It's a huge challenge 'cause we're talking about ten episodes, or almost character studies, individually featuring various characters from the Bluth family and showing where they are now and updating audiences, as we build to what we eventually expect and hope will be a movie.
"So, we need to re-acclimate everybody, and I think he's got some hilarious idea about where these characters are in the world now, four or five years later, what they've been up to, what their frame of mind is now, and how they relate to each other.
"It's pretty hilarious, outrageous stuff. Mitch is really enjoying delving back into the Bluth family."
In addition to working as an executive producer on the series, Howard also provided the narration for the sitcom.
Series star David Cross claimed last month that the Arrested Development cast are very excited to be reuniting.
