All New Episodes of Arrested Development Will Release Together
by 
Though having been announced that Arrested Development will return with an all new season to air exclusively through the Netflix Instant Streaming service before the movie arrives it remained unclear how logistically it will work. Now it is being reported that all 10 episodes will be pushed live at the same time rather than spaced out. This would be handled the same way as their first exclusive series Lilyhammer which had all 8 episodes go out at once.
The fourth season of Arrested Development is expected to begin production this summer with a target of early-to-mid 2013 for release. The movie would then presumably follow later in the year.
