VB will be back this fall, the trailer/preview for the first half (the show will become like South Park with the season split into two halves) just dropped on Adult Swim.
UPDATE: The first episode airs at Midnight on the 18th/19th of October.
It's almost time to make a Season 5 Catch-All.
This past Sunday was the 2012 Halloween Special. Fret not if you missed it, it is on again Thursday night (i think, check local listings).
You can also watch it on Adult Swim if you don't have a rinky dink cable company like me.
