Comic-Con may be over (mostly, anyway) but that doesn't mean you can't find out what went on there! The biggest bit of news is that Dark Horse will be releasing a book called The Art of the Venture Brothers
(or similar) some time in the future. We'll likely hear more about that in the future. Below are links to some articles, though you should note that they all contain a fairly minor spoiler for tonight's episode, but you've been warned nonetheless:
Devin T. Quin sent along word that he covered the Venture Bros. panel for Bleeding Cool
and naturally he's got info on what went down during the panel as well as some great photos of cosplayers waiting in line to get into it.
If brevity is what you crave then The Outhouse has what you need
. If that's still too much, Major Spoilers has an even shorter summary
. Thanks to Robert for sending those two links along.
