Jackson Publick has posted some season 2 information to his
blog:
"What I can tell you is that the Venture Bros. Season Two DVD is presently scheduled to be released April 17, 2007. Doc and I are grinding out all the supplemental materials as I write this--we've recorded commentary for every episode (some with James Urbaniak and Mike Sinterniklaas as our very special guests) which we can guarantee will be even less entertaining and more off-topic than the last set's; we're filming some live action stuff which promises to have fewer bad costumes and more dazzling special effects, and we've compiled some 30 deleted "scenes" in various states of dis-animation, many of which you'll be glad we cut but some of which are pretty funny. You are already shouting "oh boy!" I know. "
Thanks to Darren Hennessey for the news. Of course this won't be official until we hear the news from Warner Bros, but Publick's info was correct for season 1.
