Sadly, The Venture Bros. won't return for its sixth season until January 2015. But the creators may release an hour-long special in 2014 to assuage our Monarch-withdrawal.
Argh this show! It is hard to be a fan a show that takes such huge breaks between seasons. 11 years for 6 seasons. Maybe I should stop paying attention to it until say 2025 when I assume the show will finish its 8th and final season. Then I can buy the DVDs.
