I thought sitcoms, with some exceptions, generally need 100 episodes before they're syndicated. (It has been on syndication for a long time in Canada, on CBC.)
Anyway
I would think that Arrested Development's small fanbase, most of whom probably own the entire series on DVD (like me), would prevent the show from doing well on syndication. And arrested Development's story lines, which span entire seasons, aren't conducive to syndication.
